Question

The correct range for the function ƒ(x) = x − 9 if the domain is (3, -3, 0) is:

Answer 1

The correct range is thus;

(-6,-12,-9)

Explanation:

Here, we want to get the range given the domain

we simply make a substitution of the domain in the equation so as to get the range

So let us substitute the value of the domain one after the other

f(3) is 3-9 = -6

f(-3) = -3-9 = -12

f(0) = 0-9 = -9
