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.
