Question

f(x)=x^2e^15x find critical numbers

Answer 1

take the derivative of the function (use the chain rule and quotient rule) then set the derivative to zero and solve for x (remember only the top can equal zero because if you have a number divided by zero it is undefined)

Answer 2

also the end points of the interval (if you have one) are also critical numbers

Answer 3

figured it out
