Question

The graph of a polynomial p(x) is shown (a wave-like curve touching x-axis at 4 points). The number of zeroes of the polynomial p(x) is:

Accepted Answer

The number of zeroes of a polynomial equals the number of points where its graph intersects the x-axis. Here the graph cuts the x-axis at 4 points.
