For the function f(x)=x^3e^x, determine intervals of increase and decrease and the absolute minimum value of f(x)
To do this I found the derivative which is f'(x)=3x^2e^x.
Then I set it to zero:
f'(x)=0
0=3x^2e^x
How would I isolate x? And when I do, I would sub that x value into the original function to find the intervals of increase and decrease right? Also, how would I find the absolute minimum value?
