(i) The graphs of y p(x) are given in Fig. below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.

Text Solution

Verified by Experts

The correct Answer is:
i] 0 since the graph does not cut the x-axis at any point.
ii] 1 since the graph intersects the x-axis at only 1 point.
iii] 3 since the graph intersects the x-axis at 3 point.
iv] 2 since the graph intersects the x-axis at 2 point .
v] 4 since the graph intersects the x-axis at 4 points.
vi] 3 since the graph intersects the x-axis at 3 points.
