Provide an appropriate response.A colleague asserts that a calculation of the average rate of change of y with respect to x from 
to 
will always be only an approximation to the instantaneous rate of change at 
Do you agree with this assertion? Explain your answer using graphs or examples.
What will be an ideal response?
No. If y = f(x) is a line, then the average and instantaneous rates of change are identical.
