Find f if f"(x)=12x2+2 for which the slope of the tangent line to its graph at (1,1) is 3.
The Attempt at a Solution
What I did first was found f(x)=x4+x2+cx+d (cx and d being constants of integration.) and from this point I attempted solving for cx and d but was stuck here. It may just be the wording of the problem but I'm not sure where else to go. How do I know what to set f(x) equal to in order to solve cx and d?
Thank you for any suggestions/help.
