Answer:
x ≤ 4
Step-by-step explanation:
Given
x + ≤ 4 , that is
x + 2 ≤ 4 ( subtract 2 from both sides )
x ≤ 2 ( multiply both sides by 2 to clear the fraction
x ≤ 4
It is not a function.
For any positive x this graph will give two different values y, and that is not allowed to happen for functions.
Answer:
I believe the answer is x>0.2
