Find the absolute and local maximum and minimum values of [math]. If there are multiple points in a single category list the points in increasing order in x value and enter N in any blank that you don't need to use.

Absolute maxima
t = y =
t = y =
t = y =

Absolute minima
t = y =
t = y =
t = y =

Local maxima
t = y =
t = y =
t = y =

Local minima
t = y =
t = y =
t = y =
