Question
The graph of a polynomial P(x) is as shown.
Find the number of zeroes for the given graph of the polynomial.
Find the number of zeroes for the given graph of the polynomial.
Open in App
Solution
Points where the graph y = p(x) cuts or touches the x-axis are known as the zeroes of the polynomial.
The number of zeroes of a polynomial is equal to the number of times the graph y = p(x) cuts or touches the x-axis.
In this question, the graph is not intersecting the x-axis. So, the polynomial has no zeroes.
