Sketch the graph offby hand. (Do this on paper. Your instructor may ask you to turn in this graph.) Use your sketch to find the absolute and local maximum and minimum values off. (If there is not one, enter NONE.)

on [-4,0)

f(0)=16 (hole)

f(-1)=15

f(-2)=12

f(-3)=7

f(-4)=0

on [0,4]

f(0)=-1

f(1)=1

f(2)=3

f(3)=5

f(4)=7

What I was thinking:f(0)=16 is the highest point on the graph, but isn't in the top functions interval, so I put f(-1)=15 and it was marked wrong. ??

absolute maximum value_________

local minimum value=____________

The graphs don't intersect and since the top function is only from [-4,0), this part of the function is only concave down. I put 'none' and it was also marked wrong.
