Let f(x)=3x^4-2x^2+3

a) find f'(x)

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

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

• Calculus -

what does ^ mean

• Calculus -

to the power of, for example x squared or x cubed

• Calculus -

surely 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.
