Question

the plot below represents the function $f(x)$:
evaluate $f(4)$:
$f(4) = $
solve $f(x) = 4$:
$x = $

Explanation:

Step1: Find f(4) from the graph

Locate $x=4$ on the x-axis, move up to the line, the corresponding y-value is 2.

Step2: Find x when f(x)=4

Locate $y=4$ on the y-axis, move right to the line, the corresponding x-value is -2.

Answer:

$f(4) = 2$
$x = -2$
