Question

f(x)=e^x(x^2+2)

Answer 1

i got e^x(x(x+2)+2)

Answer 2

derivative?

Answer 3

you wanted to find the derivative?

then its correct.

Answer 4

f(x)=e^x(x^2+2)
f'(x)=e^x(2x)+e^x(x^2+2)
f'(x)=e^x(2x+x^2+2)

Answer 5

yes.... i don't know why you factored the x there but that doesn't matter I guess...

Answer 6

thanks i thought i did it a crazy way

Answer 7

no, it's fine. just a product rule (recalling the facts that d/dx(e^x)=e^x=integral e^x dx), all you really had to know is that the derivative of x^2+2 is 2x.

Answer 8

you have done everything correctly, you welcome.
