Greetings all,

Have a hard time with a homework question with this graph:

The problem states: Consider the section of the function shown below.

a) How many distinct (different) real zeros does the function have? ___

b) Approximate their values. _____

c) If the degree of the function is known to be 6, then state how many real zeros and how many complex zeros it would have.

Complex zeros. _____

Real Zeros. _____

d) Is it possible that this is a portion of a 7th degree function? why?

That is a lot of question that I am baffled on. Some direction or steps would be great if possible.
