Answer to Question #5126 in Abstract Algebra for Bailey
A polynomial function P(x) has degree n. the graph in the standard (x,y) coordinate plane of y = P(x) contains exactly 3 points on the x-axis. Which of the following could NOT be the value of n?
6, 5, 4, 3, 2
<img src="http:///" title="" alt=""> As the graph has 3 points of intersection with the x-axis, that's why 2 could not be the degree of the polinomial (parabola can have no more than 2 points of intersection). Numbers 6, 5, 4 and 3 can be a degree of the polinomial.
