Explanation:

Step1: Find f(4) from the graph

Locate $x=4$ on the x-axis, move up to the curve, then left to the y-axis. The corresponding y-value is 1.

Step2: Solve f(x)=4 from the graph

Locate $y=4$ on the y-axis, move right to the curve, then down to the x-axis. The corresponding x-value is 2.

Answer:

$f(4) = 1$
$x = 2$
