Answer
x-intercepts: $-2$ and $2$
y-intercepts: $-4$ and $4$
Work Step by Step
RECALL:
(1) A point where the graph touches or crosses the x-axis is called an x-intercept.
(2) A point where the graph touches or crosses the y-axis is called a y-intercept.
Notice that the graph crosses the x-axis at $x=-2$ and $x=2$.
Thus, the x-intercepts of the graph are $-2$ and $2$.
Verifying with the equation shows that when $y=0$, $x=\pm2$.
The graph crosses the y-axis at $y=-4$ and $y=2$.
Thus, the y-intercepts of the graph are $-4$ and $4$.
Verifying with the equation shows that when $x=0$, $y=\pm4$.
