4-37.

Sketch a graph of . At what point(s) will the line tangent to

*be parallel to the secant line through*

Calculate the slope of the secant between

We want to know where the slope of the tangent is the same as the slope of the secant. Recall that the slope of the tangent is also

known as , find where

*.*
