to maximize h, differentiate and set equal to 0
for part b) substitute 10 for x for part c) substitute 8 for h and solve for x
what is the answers when you differentiate? I am unsure
given f(x) = x^n f'(x) = n*x^(n-1) apply this to your function -3/64 x^2 +27
this is confusing can't you work it out I don't understand. Thanks
