#### Answer

x-intercepts: $-8$ and $8$
y-intercept: $4$

#### 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 $x=-8$ and $x=8$.
Thus, the x-intercepts of the graph are $-8$ and $8$.
Verifying with the equation shows that when $y=0$, $x=\pm 8$.
The graph crosses the y-axis at $y=4$ .
Thus, the y-intercept of the graph is $4$.
Verifying with the equation shows that when $x=0$, $y=4$.
