Question

How do you graph `f(x)=6x-15` using the information given by the first derivative?

Answer 1

The function is of the form `y=mx+c` which from early secondary school mathematics should be recognised as that of a straight line with slope `m` and `y`-intercept `-15`. You would not use, nor do you require, Calculus to provide any further insight into this function!
