To find the x-intercepts of the function, we need to plug in 0 for hx and solve for x.
Let's substitute hx with 0 in the equation:
0 = (-1/2)x^2 - 20
We can rearrange the equation to isolate x:
(-1/2)x^2 = 20
x^2 = -40
Since a square cannot equal a negative number, we can conclude that this equation has no real solutions. Therefore, the function does not have any x-intercepts. The ball's path does not intersect the x-axis.
