Question

the graph of $y = f(x)$ is shown below. which point could be used to find $f(-1)$?

Explanation:

To find $f(-1)$, we need the point on the graph of $y=f(x)$ where the $x$-coordinate is $-1$. This corresponds to the point with $x=-1$, which is point B.

Answer:

Point B (the point with $x$-coordinate $-1$)
