Answer:

x > - 4

Step-by-step explanation:

- 2x + 4 < 12 ( subtract 4 from both sides )

- 2x < 8

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

x > - 4

Range = {24, 55, 45, 77, 3, 93}

Don't forget about the curly braces.

The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.
