Given the range of the function find the corresponding domain. f(x)=7x-1 Range {-2,0,4,8}

LenaWriter [7]

f(x) = 7x - 1

-2 = 7x - 1

-2 + 1 = 7x

-1 = 7x

x = -1/7

0 = 7x - 1

1 = 7x

x = 1/7

4 = 7x - 1

4 + 1 = 7x

5 = 7x

x = 5/7

8 = 7x - 1

8 + 1 = 7x

9 = 7x

x = 9/7

So the domain is

Domain = {-1/7, 1/7, 5/7, 9/7}
