Question

PLEASE HELP ME!! THANK YOU!!

Answer 1

y
`\leq` 4,

y ∈ [-∞, 4]

Explanation:

Remember, the range of the function is all possible output values or y values.

As per the graph, it appears that the output, the y value, is less than or equal to 4. Hence:

y
`\leq` 4

or

y ∈ [-∞, 4]

is the range, both are the same, they are just different ways of writing it.
