Find the maximum and minimum values of

f(x)=x^4e^-x over [0,10]

2. Relevant equations

3. The attempt at a solution

From what I remember is you set the f' equal to 0. And that will give you two more points to test. and then you put the 0 and 10 number into the equation to find the values.

When I put 0 or 10 in i get 0 for both.

f'= (4x^3)(e^-x)+(x^4)(-e^-x)

If i set that equal to 0; I really do not know how to find the what x is.
