I need your help with this question:
The tangent line to the function f(x) at x=1 is y=3x-2. Find f(x) (without using integrals).
I know that the derivative at x=1 should be 3, but without more information, how am I suppose to find f(x) ? This is a multiple answers question, but at least 3 answers gives a derivative of 3 when putting x=1.
