    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.
