a)for what values of x in the domain does f have a relative max and amin? justify

b) for what values of x is the graph of f concave up? justify your answer

c) use the information found in parts a and b and the fact that f(-3)=0 to sketch a possible graph of f

obiously you can not see the graph but can you give me instructions on how to do it?

thanks

f has a max/min where f' = 0

f is concave up when f'' > 0. In other words, when f' is increasing.

f has inflection points where f'' = 0. In other words, where f' has a max/min.
