Question

6. Find the number of zeros of the following polynomials represented by their graphs.

Answer 1

1st figar, s answer is 2..
2nd figar, s answer is 3...

Answer 2

Solution :

i ) The curve of the polynomial meet

the X-axis at two points .

So, the number of zeroes of the

polynomial is two.

ii ) The curve meet the X-axis at

three distinct points .

So, the number of zeroes of the

polynomial is three.

iii ) The parabola never meets the

x-axis the polynomial has no zeroes.

iv ) The curve of the polynomial

meet the X-axis at only one point.

So, the number of zeroes of the

polynomial is one .

v ) The parabola meets x-axis at only

one point .

So, it has only one zero.
