part 2. Algebraically find the inverse of the function
1. f(x) = -3(x - 4)^2 - 6
2. y = sqrt (x - 4)^2 + 3
3. y = 4 cube root (x)
Answers
Answer:
1. f⁻¹(x) = ±²√(-⅓(x + 6)) + 4
2. y = ²√(x–3) + 4
3. y = (x/4)³
9514 1404 393
Answer:
f⁻¹(x) = 4 ±(1/3)√(-3x-18)y = (x -3)² +4y = x³/64Step-by-step explanation:
To find the inverse function, solve for y the equation ...
x = f(y)
__
1.
[tex]x=f(y)\\\\x=-3(y-4)^2-6\\\\x+6=-3(y-4)^2\qquad\text{add 6}\\\\\pm\sqrt{\dfrac{x+6}{-3}}=y-4\qquad\text{divide by -3, square root}\\\\4\pm\dfrac{1}{3}\sqrt{-3(x+6)}=y\qquad\text{add 4, rationalize the denominator}\\\\\boxed{f^{-1}(x)=4\pm\dfrac{1}{3}\sqrt{-3x-18}}\qquad\text{simplify the radical}[/tex]
__
2.
[tex]x=\sqrt{y-4}+3\\\\x-3=\sqrt{y-4}\qquad\text{subtract 3}\\\\(x-3)^2=y-4\qquad\text{square both sides}\\\\\boxed{y=(x-3)^2+4}\qquad\text{add 4}[/tex]
__
3.
[tex]\displaystyle x=4\sqrt[3]{y}\\\\\frac{x}{4}=\sqrt[3]{y}\\\\\left(\dfrac{x}{4}\right)^3=y\qquad\text{cube both sides}\\\\\boxed{y=\dfrac{x^3}{64}}[/tex]

A middle school band uses a company to manage its fundraisers. The company charges a fee of $260 per fundraiser for its services. For the first fundraiser of the year, the band is selling insulated cups with school logos on them for $10.50 each. The goal of the fundraiser is to raise at least $1000.00. The following inequality represents this situation, where c stands for the number of cups
Answers
Answer:
Step-by-step explanation:
10.5c>or equal to 1260
Answer:
I don't see any inequality or a question.
Step-by-step explanation:
I suspect you want to know the minumum number of cups to sell in order to raise $1000 and pay off the company its $260
c(10.5) - 260 > 1000
c > (1000 + 260) /10.5
c > 120 cups
