Determine whether the graph could be the graph of a polynomial function. If it could be, list the real zeros and state the least degree the polynomial can have.

A coordinate system has a horizontal x-axis labeled from negative 5 to 5 in increments of 1 and a vertical y-axis labeled from negative 5 to 5 in increments of 1. From left to right, a curve rises at a decreasing rate in quadrant 3, crossing the x-axis at x = negative 1 comma and crossing the y dash axis at approximately y equals 4.5 to a maximum in quadrant 1 comma falls and crosses the x dash axis at x equals 2 to a minimum in quadrant 4 comma and rises at an increasing rate comma crossing the x dash axis at x equals 3.
Select the correct choice below and fill in any answer boxes within your choice.
A.
The graph shows a polynomial function. The real zero(s) is/are nothing. The least degree the polynomial can have is nothing.
(Use a comma to separate answers as needed. Round to the nearest integer as needed.)
B.
The graph does not show a polynomial function.
