Question

EXERCISE 2.1
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 1

Answer:

For any quadratic polynomial ax²+bx+c the zeroes are precisely the x- coordinates of the points where the graph of y = ax² + bx +c intersects the X- axis. It is Clear from the graph that curve intersect the x-axis at 3 points. Hence the number of zeros of the polynomial y = p(x) are three
