Graph a Graph b The graphs of the functions a and b are show

                Graph a                                                                                     Graph b

The graphs of the functions

a

and

b

are shown above. For each graph, find the absolute maximum and absolute minimum. If no such value exists, write \"None\".

Assume that the dashed line shown is a vertical asymptote that the graph does not cross.

Absolute maximum a:                                                                                     Absolute maximum b:

Absolute minimum a:                                                                                      Absolute minimum b:

Solution

from the graphs

Absolute maximum a: NONE   

Absolute minimum a: absolute minimum value =-4 at x =4

Absolute maximum b: absolute maximum value =4 at x =2

Absolute minimum a: absolute minimum value =-3 at x =-1
