For the function f(x) whose graph is shown below, what is the value of f(5)?

Answers

f(5)=2 you look at the x-axis and find 5 which is in the right side then find the point on the line that touches and you will see it’s 2.

We want to look at the given graph to estimate the value of f(5). We found that: f(5) = 2

In the coordinate axis, we can see a blue curve, which represents the function f(x).

To find the value of f(5), first, we need to locate the value x = 5 on the horizontal axis.

Once we find it, we need to move vertically until we meet the curve.

Once we meet the curve, we move horizontally until we meet the vertical axis, that intersection gives the value of the function when evaluated in x = 5.

By this method we can see that: f(5) = 2
