Question 1
The graphs of y = p(x) are given below, for some polynomials p(x). Find the
number of zeroes of p(x), in each case.
(i) and (ii)

(iii)

(iv)

(v)

(vi)

Solution:
The zero’s of the polynomial are the points where the graph meet x axis in the Cartesian plane. If the graph does not meet x axis ,then the polynomial does not have any zero’s.

Since it does not intersect x-axis ,it does not have any zero’s

Since it intersect x-axis once ,it has one zero

Since it intersect the x-axis thrice,it has three zero’s

Since it intersect the x-axis two,it has two zero’s

Since it intersect the x-axis four times,it has four zero’s

Since it intersect the x-axis thrice,it has three zero’s
