Hi, in math class, we were assigned a challenge problem that has to do with finding the volume of a box. My function is:
f(x) = 4x3 - 88x2 + 480x
I found that the maximum value of this function is 768 (the maximum volume), but I want to know how to solve for `x`. This is what I have:
768 = 4x3 - 88x2 + 480x
192 = x3 - 22x2 + 120x
How would I continue to solve for `x`?
