Question

Zeroes of a polynomial can be determined graphically. Number of zeroes of a polynomial p(x) is equal to the number of points where the graph of the polynomial

Answer 1

The zeroes of the polynomial is determined when the given point intersects the x axis. The point intersecting the x axis are the zeroes of the polynomial. Ex. If the given polynomial the points touches or intersect the x axis two times then the given polynomial has two zeroes. Similarly the no. Of points intersecting the x axis is the no. Of zeroes of the polynomial.
