Question

Select the correct answer.

If the factors of quadratic function g are (x − 7) and (x + 3), what are the zeros of function g?
A.
-7 and -3
B.
-3 and 7
C.
3 and 7
D.
-7 and 3

Answer 1

The correct option is (b).

Explanation:

We are given with the factors of quadratic function. They are as follows :

(x − 7) and (x + 3)

It is required to find the zeroes of function g.

To find zeroes of function, it is required to put the factors equal to 0 i.e.

`(x-7)=0\\\\x=7`

and

`(x+3)=0\\\\x=-3`

From above calculations, we can say that the zeroes of function g are 7 and (-3). Hence, the correct option is (b).
