If the graph of the polynomial p(x) is as shown in the figure, then the number of positive zeroes of p(x) is
Open in App
Solution
The correct option is D 1
The graph of cuts the x-axis at 3 points.
Therefore, the total number of real zeroes is 3.
Out of these, only one is positive.
Therefore, the number of positive zeroes of p(x) is 1.
Hence, the correct answer is option (d).
