## Chapter 2 Polynomials Exercise 2.1

**Question 1: The graphs of y = p(x) are given in Fig. 2.10 below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.**

**Answer:**

i) No zeroes as the graph doesn’t touch the x-axis.

ii) 1 zero as the graph touch the x-axis only 1 time.

iii) 3 zeroes as the graph touch the x-axis only 2 times.

iv) 2 zeroes as the graph touch the x-axis only 3 times.

v) 4 zeroes as the graph touch the x-axis only 4 times.

vi) 3 zeroes as the graph touch the x-axis only 3 times.
