# Math Help - Differentiate the function

1. ## Differentiate the function

Okay so it is with respect to X

y=9x^2-8x+4+1/x

So I am thinking you have to times the exponent?? 18x-8+4...and then I am lost. Any help?? Thanks?

2. Differentiate each term using the rule $\displaystyle \frac{d}{dx}(a\,x^n) = na\,x^{n-1}$ and recall that $\displaystyle \frac{1}{x} = x^{-1}$.
