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)

polynomials 1

Answer:- Number of zeroes = 0, since the line is not intersecting the x-axis

(ii)

polynomials 2

Answer:- Number of zeroes = 1, since the line intersects the x axis once.

(iii)

polynomials 3

Answer:- Number of zeroes = 2, since the line intersects the x axis twice.

(iv)

polynomials 4

Answer:- Number of zeroes = 2

(v)

polynomials 5

Answer: Number of zeroes = 4

(vi)

polynomials 6

Answer: Number of zeroes = 2
