Step-by-step explanation
By definition, the range of a function is the complete set of all possible resulting values of the dependent variable (y, usually) after we have substituted the domain.
From the graph, we see that the function takes the y values:
• from y = -2 (including the value),
,
• to y = 5 (without including the value).
Taking this data into account, the interval for the range is:
Answer
(c) ≤ (less than or equal to)
(d) < (less than)
