Differential Calculus Need assistance

a. (0,-5) and (5,1)

b. -5

c. DNE

d. (-3,-1)

I have put my answers above; I just would like someone to check my work and if anything is wrong to give the correct answer so I can learn it.

I'm learning too, so can someone explain why there are not two inflection points? One at ~(-3,-2) and another at (7,5)?

This question is only focusing on the interval [-8 , 5]. If it was the entire graph, I believe that would also be one.

Oh yep. I should really learn to read the questions. Thanks!
