Victoria Benson · Answer 1

The range is found by plugging in the values of the domain into 2x - 1

So for x = - 2, f (x) = 2 (-2) - 1 = - 5

The range will consist of - 5 and the other 3 values of f (x) found for x = 0, x=2 and x=4.

Jasiah Barrett · Answer 2

The range is how much it spans in f (x), f (x) is a line, it has no max/min, so it's enough to substitute the least and greatest values of your domain:

f (-2) = - 5, f (4) = 7,

Range = [-5,7]
