First of all,

Thank you for the help. Secondly, my computer would not work and as you mentioned, was done one the phone. Unfortunately I was not able to make corrections yesterday and with the limited view screen, It was pretty hard to proof read as everything I typed had a time delay.

But yes, you retyped correct, and it was what I was asking.

Now to your question: product rule for second problem.

You'd think we ( the entire) class would know, but unfortunately we are faced with a math teacher who gives very little explanation.

In other words, when one looks at the problem at hand,problem 2- in where you pointed to use the product rule, do we first take the derivative of f'(x) and plug it (multiply it by (x^2) OR take the derivative of (x^2) as well and use the product rule...?

Thank you again, Jen
