Question

the graph of $y = f(x)$ is shown below. which point could be used to find $f(-5)$?
answer
$circ$ a
$circ$ c
$circ$ d
$circ$ b

Explanation:

For a function $y=f(x)$, $f(-5)$ represents the $y$-value when $x=-5$. We need the point on the graph with an $x$-coordinate of $-5$. Point $C$ has an $x$-coordinate of $-5$, so it is the point used to find $f(-5)$.

Answer:

C
