function: f(x)= -x^2+2

true or false:
when f(x) =2, x= -2

Answer:

True

Explanation:

Step 1: Define

f(x) = -x² + 2

x = -2

Step 2: Substitute and Evaluate

f(-2) = -(-2)² + 2

f(-2) = -4 + 2

f(-2) = -2

Source 1

"Christendom had recovered from . . . when the Tartar cataclysm had threatened to engulf it. The Tartars themselves were already becoming an object of curiosity rather than of fear. . . . The frail Latin throne in Constantinople was still standing, but tottering to its fall. The successors of the Crusaders still held the Coast of Syria. . . . The jealousies of the commercial republics of Italy were daily waxing greater. The position of Genoese trade on the coasts of the Aegean was greatly depressed . . . Venice had acquired [power there by expelling] the Greek Emperors. . . . But Genoa was biding her time for an early revenge, and year by year her naval strength and skill were increasing. Both these republics held possessions and establishments in the ports of Syria. . . . Alexandria was still largely frequented in the intervals of war as the great emporium of Indian wares, but the facilities afforded by the Mongol conquerors who now held the whole tract from the Persian Gulf to the shores of the Caspian and of the Black Sea, or nearly so, were beginning to give a great advantage to the caravan routes.”

Henri Cordier’s annotated translation of The Travels of Marco Polo, 1920

"Throughout the twelfth century there were many signs that the European intelligence was recovering courage and leisure, and preparing to take up again the intellectual enterprises of the first Greek scientific enquiries and such speculations as those of the Italian Lucretius. The causes of this revival were many and complex. The suppression of private war, the higher standards of comfort and security that followed the crusades, and the stimulation of men’s minds by the experiences of these expeditions were no doubt necessary preliminary conditions. Trade was reviving; cities were recovering ease and safety; the standard of education was arising in the church and spreading among laymen. The thirteenth and fourteenth centuries were a period of growing, independent or quasi-independent cities; Venice, Florence, Genoa, Lisbon, Paris, Bruges, London, Antwerp, Hamburg, Nuremberg, Novgorod, Wisby and Bergen for example. They were all trading cities with many travellers, and where men trade and travel they talk and think. The polemics of the Popes and princes . . . were exciting men to doubt the authority of the church. . . .

The Arabs [began] restoring Aristotle to Europe, and . . . [European princes like] Frederick II acted as a channel through which Arabic philosophy and science played upon the renascent European mind.”

H. G. Wells, A Short History of the World, 1922

Refer to the passage.

"They [the Mongols] came down upon the city and killed all they could, men, women and children, the old, the middle-aged, and the young. Many of the people went into wells, latrines, and sewers and hid there for many days without emerging. Most of the people gathered in the caravanserais [inns] and locked themselves in. The Tatars [Mongols] opened the gates by either breaking or burning them. When they entered, the people in them fled upstairs and the Tatars killed them on the roofs until blood poured from the gutters into the street; ‘We belong to God and to God we return’ [Qur'an, ii, 156]. The same happened in the mosques and cathedral mosques and dervish convents. . . . And Baghdad, which had been the most civilised of all cities, became a ruin with only a few inhabitants, and they were in fear and hunger and wretchedness and insignificance.”

(1) Hong Kong is one of the most densely populated places on Earth: people crowd into tiny living spaces, some with only a bed, a hot plate, and a toilet. (2) The city is made up of more than 200 islands, and there is no more available land to house its people. (3) To solve this land shortage problem, officials have proposed a radical solution: creating a whole new island. (4) The East Lantau Metropolis would be built on land reclaimed from the sea and would house 1.1 million people.

(5) A different problem faces the people of Kiribati—a nation in the central Pacific Ocean made up of 33 islands (most of which are less than twenty feet above sea level). (6) Because of rising sea levels, some inhabitants have already had to abandon their homes. (7) New islands will have to be built to ensure a safe future for its citizens, because science indicates that Kiribati will go underwater within the century.

(8) Artificial islands have been seen as solutions for a number of problems in recent decades. (9) The city of Dubai has been constructing a luxurious palm-tree-shaped series of islands to house hotels. (10) Osaka, Japan, built an island off its coast to relieve its overcrowded airport. (11) The Maldives, Malaysia, and Seoul have all built or have plans to build artificial islands to expand their territory.

(12) So, is building artificial islands a good solution for modern-day challenges? (13) Not everyone thinks so. (14) Constructing artificial islands destroys the coral reefs that nourish fisheries and protect the coastline from the impact of waves; it also destabilizes precious coastal ecosystems. (15) Building on unstable dredged sediments also endangers human inhabitants, especially in areas prone to earthquakes.

The writer wants to provide relevant support for the claim made in sentences 12 and 13. Which of the following sentences, if added after sentence 13, would most effectively accomplish this goal?

A) According to the Australian Bureau of Meteorology’s National Tidal Centre, there has been an average sea level rise of 7.3 millimeters a year around low-lying islands like Kiribati in the past few decades.

B)A professor of biology at Old Dominion University, Kent Carpenter, notes that poaching of giant clams does more damage to marine ecosystems than island building does.

C)Marine biologists contend that the urban sprawl spreading into the oceans inevitably causes havoc for marine organisms and their habitats.
Marine biologists contend that the urban sprawl spreading into the oceans inevitably causes havoc for marine organisms and their habitats.

D)The government of South Korea expected to have 300,000 residents in the utopian smart city built on the artificial island of Songdo.


E)Environmental scientists at Macquarie University in Sydney, Australia, have noted that those building artificial islands can use techniques like silt curtains to help minimize the environmental impact of these projects.
