(a) $f(-2) = 3$ (b) $f(0) = 3$ (c) $f(1) = 3$ (d) $f(4) = 3$
RECALL: If $(a, b)$ is on the graph of the function $y=f(x)$, then $f(a) = b$. (a) The graph of the function $y=f(x)$ contains the point $(-2, 3)$. Thus, $f(-2) = 3$. (b) The graph of the function $y=f(x)$ contains the point $(0, 3)$. Thus, $f(0) = 3$. (c) The graph of the function $y=f(x)$ contains the point $(1, 3)$. Thus, $f(1) = 3$. (d) The graph of the function $y=f(x)$ contains the point $(4, 3)$. Thus, $f(4) = 3$.
