When is a function not differentiable?(2.1 #80)

 When is a function not differentiable? (p 109 (2.1) number 80

 A function may not have a derivative.  After all slope is rise over run, and if it is a vertical line, it will have no slope.  Here we have an example that has no slope at x=0, since the slopes from the left and the right do not agree (so the limit does not exist, so neither does the slope!
