What is the range of the function

Answer:
The range of the function is:[tex]\{x| x=-9, -3, 0, 5, 7\}[/tex]
Step-by-step explanation:
Consider the provided function.
The range of the function is the set of output values which a function can produce, or we can say that the range is the set of y values which a function can produce.
Now consider the provided function:
[tex]\{(-2,0), (-4,-3), (2,-9), (0,5), (-5,7)\}[/tex]
In the above function all the set of y values is the range of the function and the y values are:
0, -3, -9, 5, and 7
Thus, the range of the function is:[tex]\{x| x=-9, -3, 0, 5, 7\}[/tex]
