need some help with this question question in picture

Answer: Choice C) [tex]-\infty < y \le 7[/tex]
Explanation:
The range is the set of possible y outputs of a function.
We see that the highest this graph goes is y = 7.
So the range as an inequality is [tex]y \le 7[/tex] which is the same as saying [tex]-\infty < y \le 7[/tex]
Side note: This would convert to the interval notation (-infinity, 7]
