1. f(x) = 5x +4
for range = {5, 6, 7, 8}
determine the domain

see explanation

Step-by-step explanation:

Given the range of f(x), find the domain by equating f(x) to each of the values in the range, that is

5x + 4 = 5 ( subtract 4 from both sides )

5x = 1 ( divide both sides by 5 )

x =

5x + 4 = 6 ( subtract 4 from both sides )

5x = 2 ( divide both sides by 5 )

x =

5x + 4 = 7 ( subtract 4 from both sides )

5x = 3 ( divide both sides by 5 )

x =

5x + 4 = 8 ( subtract 4 from both sides )

5x = 4 ( divide both sides by 5 )

x =

Thus

domain = { , , , }

its a little blurry tbh
