Hello MHF,

I am stuck on part c of this question and am not 100% sure on a and b either. There is a table involved. It is attached.

a) What are the x-coordinates of all absolute maximum and absolute minimum points of

on the interval

. Justify your answer.

b)What are the x-coordinates of all points of inflection of

on the interval

? Justify your answer.

c) Sketch a graph that satisfies the given properties of

.

a-answer) i got

for a maximum because the

goes from negative y values to 0 back to negative y values. is this correct?

b-answer) point of inflections occurs when

and thats and

, I don't think there are any other points, correct?

c-answer) i could never figure out how to do that on MHF but i have seen other people do it. All my graphs don't seem to work, but from the chart i think there are 2 separate functions?

any help, especially with c would be greatly appreciated. Thanks.
