What is the zero of the following function ?
A) x=5
B) x=1
C) x=-1
D) x=-5

This graph clearly shows that the curve intersects the x-axis at (-5,0). This point is the "zero" of the function.
The answer is where the curve intersects the x-axis, which is at (-5,0). This point is the "zero" of the function. Hope this helps:)
