Question

Can someone tell me if this is correct?

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

f(x) = 7x^2 + 3
f'(x) = 14x

f(x) = 1 / x
f'(x) = -1 / x^-2

Answer 1

Correct, except the last one I'm not sure if you meant \[\Large f'(x) = \frac{ -1 }{ x^{-2} }\] as that is not correct, the 2 should be positive.

Answer 2

that is unfortunately what I meant, I see tha mistake, thanks :)
