Answer:

Step-by-step explanation:
First, the formula for the volume of a sphere is:




![r = \sqrt[\leftroot{-2}\uproot{2}3]{\frac{3}{4\pi}V}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B%5Cleftroot%7B-2%7D%5Cuproot%7B2%7D3%5D%7B%5Cfrac%7B3%7D%7B4%5Cpi%7DV%7D)

To find the X intercept make y =0. Then factor out a negative on the side with the equation for each of the terms, so it becomes
0=-(x^2+x+3)
0=(x^2+X+3)
0-3=(x^2+X)
-3=x(X+1)
-3=X, X intercept -3,0
-3=(X+1)
-4=X, X intercept -4,0.
These are possible X intercepts you can check by using quadratic formula as well.
