Remember that a solution set is the same thing as saying the value(s) of x (or whatever input variable) that satisfy something. Please don't try to do these algebraically; visualize the function by first making the inequality a roots argument and then see what values satisfy the statement. For sketching the function you have options:
1. Find roots and see if the function is opening up or down.
OR
2. Convert to a form where the transformations are easy to see and then sketch it (you may still need to find roots for the solution set to the inequality).
Either way, roots are important!
