Question

If f(x) = 8x^2 − x^3, find f '(1) and use it to find an equation of the tangent line to the curve y = 8x^2 − x^3 at the point (1, 7)

Answer 1

What part do you not understand?

Answer 2

I don't understand how to find the answer. My online homework module walked me through a similar problem earlier but when I followed the same steps I came up with an incorrect answer.

Answer 3

I'm assuming I made a mistake but I"m not sure where I went wrong

Answer 4

Alright. What did you get for the derivative? Maybe you computed it wrong.

Answer 5

I think I see where I screwed up. Thanks for replying!

Answer 6

Alright, that's good then.
