Answer:
Range = {-1, 1, 3}
Step-by-step explanation:
The question asks for the range.
The function given is
[tex]y=x-5[/tex]
The domain is the set of 3 numbers:
Domain = {4,6,8}
We need to find the range.
First, the range is the set of all y-values for which the function is defined.
When we will be given the domain with a set of numbers, the range would be the numbers that we get when we evaluate the the function at those numbers.
So, we evaluate the function (y-values) at x = 4,6, and 8.
At x = 4:
[tex]y=x-5\\y=4-5\\y=-1[/tex]
At x = 6:
[tex]y=x-5\\y=6-5\\y=1[/tex]
At x = 8:
[tex]y=x-5\\y=8-5\\y=3[/tex]
Thus, the range is:
Range = {-1, 1, 3}
