Given f(x) =
e^3x
We need to find the first derivative f'(x) using the chain
rule.
We will assume that u= 3x ==> u' = 3
==> f(x)
= e^u
==> Now we will differentiate:
==> f(x) =
(e^u)' = u' * e^u du
==> Now we will substitute with x.
==> f(x) =3 ** e^3x = 3*e^3x
Thenthe derivative of
f(x) is f'(x) = 3*e^3x
