instantaneous rate of change is derivative f'(x)=10x+2 now plug in x=1
Since this has been posted in the Pre-Calculus section, I doubt that the OP knows what a derivative is, or how to calculate it. I would say at a Pre-Calculus level, it is enough to evaluate the difference quotient with a small change in , say . ?
