Can someone help me with this math homework please!

Answer:
1 C
2 A
3 D
4 B
Step-by-step explanation:
The y-intercept is whenever the graph crossses the y-axis, so the input will always be 0.
When f(x) > 0, that's when the output is greater than 0, so it would be above the x-axis.
The x-intercept is whenever the graph crosses the x-axis, so the output will always be 0.
Hope that helps (●'◡'●)
