Step by Step Solution

Step 1

The purpose of this question is to show you that the ideas behind x and y intercepts are also applicable to non-linear equations.

First, let's find the y-intercept. From the picture, we can see that the graph crosses the y-axis at the y-coordinate of -4.

Hence, the y-intercept is -4.

Step 2

Next, let's find the x-intercept. From the picture, we can see that the graph crosses the x-axis at the x-coordinates of -2 and 2.

Hence, the x-intercepts are -2 and 2.

Step 3

Now, we have the:

y-intercept = -4
x-intercepts = -2 and 2

Clearly, the answer is A.
