Answer:
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.

and

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