Question

The graph of the function f is shown below Find one value of x for which f(x) =2 and find f(2)A- One value of X for which f(x)=2: B- f(2) =

Answer 1

To find the corresponding x where the function assumes a certain value, we draw a horizontal line on the desired function value. For f(x) = 2, we have:

The intercept between the horizontal line and our graph happens at (0, 2), therefore, we have:

$f(x)=2\implies x=0$

To evaluate graphically a function, we check the corresponding value for the desired x value on the horizontal axis. For x = 2, we have:

Then

$f(2)=1$
