3-137.

For the absolute value function shown at right, something interesting happens to the tangent line of the function at* *. Can you draw more than one tangent line at

*? Do you think this function has any valid tangent lines at*

*?*

Consider the slope as and then consider the slope as

*.*

From the left, the slope appears to be

From the right, what does the slope appear to be?
