If the range is {6,4,2} in the function f(x)=2x what is the domain

{3,2,1}

Step-by-step explanation:

Domain is the set of x-values

Range is the set of y-values

Also, domain means what you put into the function (input) and range is what we get (output).

The output is given as {6,4,2} and asks for INPUT >>> What values we put into x that gives us 6, 4, and 2...

Let's figure it out.

f(x) = 2x

6 = 2x

x = 6/2 = 3

f(x) = 2x

4 = 2x

x = 4/2 = 2

f(x) = 2x

2 = 2x

x = 2/2 = 1

So the domain would be {3,2,1}
