Question
The graph of a polynomial p(x) cuts the X-axis at 3 points and touches it at 2 other points. It also touches the Y-axis at 1 point. The number of zeroes of p(x) is
Solution
The number of zeroes of a polynomial is given by the number of times it intersects or touches the x-axis. In this case, the polynomial p(x) cuts the x-axis at 3 points and touches it at 2 other points. Therefore, the number of zeroes of p(x) is 3 (from the points where it cuts the x-axis) + 2 (from the points where it touches the x-axis) = 5. The point where the graph touches the y-axis does not count as a zero of the polynomial, because zeroes are only counted from the x-axis. Therefore, the number of zeroes of p(x) is 5.
