SAT Question ad376f1a: Nonlinear Functions answer and explanation with Desmos solution

Choice D is correct. Because the graph of $y=f\left(x\right)$ is shown, the value of $f\left(0\right)$ is the value of $y$ on the graph that corresponds with $x=0$. When $x=0$, the corresponding value of $y$ is $3$. Therefore, the value of $f\left(0\right)$ is $3$.
