1. The problem asks to find the value of $x$ when $f(x) = 3$ using the graph of the function $f$. 2. The function value $f(x)$ represents the $y$-coordinate on the graph for a given $x$. 3. To find $x$ when $f(x) = 3$, locate the horizontal line $y=3$ on the graph and find the $x$-coordinate(s) where the graph intersects this line. 4. According to the graph, the curve intersects the line $y=3$ at approximately $x=2$. 5. Therefore, the solution is $x = 2$ to the nearest integer. Final answer: $x = 2$
