Question

9The domain of the function f(x) = x +42 - 12is all real numbers a except for where a equals 1

Answer 1

Answer: 3

Step-by-step explanation:

The denominator of a fraction can not have the value zero.

So,

4x - 12 ≠ 0

4x ≠ 12

x ≠ 12/4

x ≠ 3

The domain of the function is all real numbers x except for where x equals 3.
