How would I find the derivative of this function: ?
I'm only supposed to use the power rule and I'm having a little trouble.
Thanks! Back to the actual question, however, I had to write an equation for the tangent of at (3,9)
What I'd normally do is set to find the slope of the tangent, which would equal to and set that equal to to find the equation in standard form.
The back has the final answer as , can anyone tell me if I'm doing anything wrong or if its a mistake in the book? Thanks!
