## Calculus, 10th Edition (Anton)

$y' = 3x^2e^x+x^3e^x$
In order to derivate this function you have to apply the product rule $\dfrac{d}{dx}(ab) = a'b+ab'$ Then let's identify a and b and derivate them $a=x^3$ $a' = 3x^2$ $b=e^x$ $b'=e^x$ Then substiute in the formula, simplify and get the answer: $y' = 3x^2e^x+x^3e^x$
