--- function
Step-by-step explanation:
Given

Solving (a): The domain
The x values represent the domain.
Hence, the domain is:

Solving (b): The range
The y values represent the range
Hence, the range is:

Solving (c): The function
By observation, we can see that for all values of x the value of y remains unchanged (-5)
Hence, the function is:

Answer:
-3/6 -2/6 -1/6 0/6 1/6 2/6
Add 21 to both sides, so you get 9z = 81
