Question

Find the derivative of the following function
f(x)=(4x^3+3x^2)/x

I just need help to put this function into a form where I can find the derivative. How do I get the x on the bottom to the top?

Answer 1

To eliminate the x at the bottom, simply divide each of the terms at the top by x.

Answer 2

Okay so would it be 4x^2+3x ?

Answer 3

Yes, you are correct. Now differentiate.

Answer 4

Okay, so after it would be 8x+3 ?

Answer 5

Yes, you have found f'(x). Good work!

Answer 6

Thanks !!

Answer 7

You're welcome :)
