Question

Determine the zeroes of the quadratic function whose graphs are given below:​

Answer 1

1. zeros are -2 and 1

2. zeros are -1 and 3

3. zeros are -3 and 1

4. zeros are -1

5. no zeros

6. no zeros

Explanation:

Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
