Hello,(adsbygoogle = window.adsbygoogle || []).push({});

It is given that h(x) = f(x)g(x). It then tells me to write a formula for h'(2).

I know that h'(x) = f'(x)g(x) + f(x)g'(x), using the product rule.

So I assumed that h'(2) = f'(2)g(2) + f(2)g'(2)

Is this correct? Does the product rule simply allow me to do this? It seems to simple.

Thanks in advance,

Greg
