Answer
x-intercepts: $0$ and $4$.
y-intercept: $0$
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=0 and x=4.
Thus, the x-intercepts of the graph are 0 and 4.
The graph crosses the y-axis at y=0.
Thus, the y-intercept of the graph is 0.
