D.{-12,-14}
E.{0,5}
Answer:
Option A is correct
{2, 4} is, the function's domain.
Step-by-step explanation:
Domain is the set of all values of x for which function f(x) is defined.
Range is the set of all complete value of f.
Given the function:
The range of the function is {7, 9}
When f(x) = 7
then;
Subtract 5 from both sides we have;
x = 2
When f(x) = 9
then;
Subtract 5 from both sides we have;
x = 4
⇒Domain = {2, 4}
Therefore, the function's domain is, {2, 4}
