Question

Y = x - 5

Domain= {4, 6, 8}

Answer 1

Range = {-1, 1, 3}

Explanation:

The question asks for the range.

The function given is

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:

At x = 6:

At x = 8:

Thus, the range is:

Range = {-1, 1, 3}
