Question

Below are several points on the graph of a polynomial. Which of the following statements are true about the graph of this polynomial?

Answer 1

Notice that we need to look for the intervals of x and also for the intervals of y. We can observe that there is a minimum between x = 0 and x = 1 because the graph is descending and then ascending and also the graph has a maximum value between y = -3 and y = -1.
