    Domain represents (x)..range represents f(x) or the solution..thus if you plug in each value for f(x) and solve for (x) you will have your domain values...

    For example, your first range is -20 plug this in the equation to find your domain (x) so it will be like this: f(x) = 4 − 4x -20 = 4 − 4x now, simplify this and solve for x. Then apply this method to get the corresponding domain for each given range in your question.
