How did you get your answer of 768? It should actually be about 774 by the way.
Have you learnt about differentiation?
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) = 4x^{3} - 88x^{2} + 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 = 4x^{3} - 88x^{2} + 480x
192 = x^{3} - 22x^{2} + 120x
How would I continue to solve for `x`?
I used my graphing calculator, but then I just realized that decimals are involved too. All I need is the `x` value and I can't find that in my table.
