Answer: D) All real numbers greater than or equal to -4.
Step-by-step explanation:
The lowest point occurs when y = -4, which is where the vertex is located.
The range consists of y values such that y = -4 or y > -4. We can shorten that last sentence to say
. So y is greater than or equal to -4.
As you can probably tell, the range is the set of all possible outputs of a function.
