Question

Match the following polynomials with the maximum number of times the graph intersects the X axis.

• A. 3
• B. 4
• C. 1

Answer 1

The graph of a polynomial of degree 'n' can cut X axis at most at 'n' values.
The first polynomial is of third degree and hence can cut the X axis at 3 points.
similarly the second at 4 and the last at one point.
