Question 1:
The graphs of 𝑦 = (𝑥) are given in following figure, for some polynomials
(𝑥). Find the number of zeroes of (𝑥), in each case.

 

Solution:
(i) Since the graph does not cut the x – axis at any point. Therefore, the number of zeroes is 𝟎.
(ii) As the graph intersects the x -axis at only 𝟏 point. Therefore, the number of zeroes is 𝟏.
(iii) Since the graph intersects the x-axis at 𝟑 points. Hence, the number of zeroes is 3.
(iv) Since the graph of (𝑥) intersects the x-axis at 𝟐 points. So, the number of zeroes is 𝟐.
(v) Since the graph of (𝑥) intersects the x-axis at 𝟒 points. Therefore, the number of zeroes is 𝟒.
(vi) As the graph intersects the x-axis at 𝟑 points. So, the number of zeroes is 𝟑.
