# Math Help - Differentiate

1. ## Differentiate

Find the derivatives of the following:

(1) y = 3x

(2) f(x) = 16x

I know the answer (1) is y ' = 3 and the answer
for (2) is f ' (x) = 16.

My question is:

How do I get those answers?

Do I apply the product rule or power rule?

Do you suggest the chain rule?

You are applying the power rule. $y=3x^1$ so $y'=3(1)x^0=3$. Same thing for the second one.
