Question

13. The graph of = () are given below for some polynomials ().Find the number of zeros of () in each case.



​

Answer 1

Answer:

1 has 3 zeros

2 has 5 zeros

Step-by-step explanation:

the number of zero in the graph can be represented by the number of times the parabola intersect the x axis

as in 1st graph it intersect 3 times in x-axis so the 1st graph has 3 zeros.

And in 2nd graph the parabola intersect x axis 5 times ,so it has 5 zeros.
