the graph of $y = f(x)$ is shown below. according to the graph, what is $f(-1)$?
the graph of $y = f(x)$ is shown below. according to the graph, what is $f(-1)$?
Answer
Explanation:
Step1: Locate x = -1 on x-axis
Find the point on the graph where the x-coordinate is -1. This is point D.
Step2: Identify y-value of the point
The y-coordinate of the point at x=-1 is -2, so $f(-1)$ equals this y-value.
Answer:
$-2$
