a) find f'(x)

Answer: f'(x)=12x^3-4x

b) find the slope of the line tangent to the graph of f at x=3.

Answer:312

So I got those firs two right but what I need help with is part C which is

c) find an equation of the line tangent to the graph of f at x=3

**Steve**, Friday, January 25, 2013 at 3:49pmsurely by now you know that the line through (h,k) with slope m is

y-k = m(x-h)

you have h=3,m=312, and k=f(3)

plug and chug.
