The question is to find the antiderivative. I'd assume it would be inverse tangent X -13. Am I correct?
2) (1 pt) Given that the graph of f(x) passes through the point (5,5) and that the slope of its tangent line at (x,f(x)) is 4x +5 what is f(3)? | 1. No. Try  . Do you see why?
2.  . Substitute (5, 5) to get the value of C. Then substitute x = 3 to get the required value of y.
