Find what x would be if y is 7, them find what x will be if y is 9.
If y is 7, x will be 2.
If y is 9, x will be 4.
So the answer is 2,4 or A.
A domain x ∈ {2, 4 }
To find the domain, that is the values of x that produce the values in the range , solve for x , that is
x + 5 = 7 ⇒ x = 7 - 5 = 2
x + 5 = 9 ⇒ x = 9 - 5 = 4
