Answer:
y ≥ -3
Step-by-step explanation:
When we talk of the range of a function, we are referring to the y-values which are possible for the function to take
From the diagram, we can see that the y-values starts from -3 which shows it is inclusive and extends from it
So, the possible range values of the function are values of y starting from -3 and above it
In inequality sign, we can have this as
y ≥ -3
