If 18 bags of popcorn is $13.45 then how much money is only 1 bag of popcorn?

Ecause for your equation, each value of y is the parent function's y-value, |x|, minus 4, each point is shifted down 4 units. So this will be a "V" that is shifted down so the vertex is at (0, -4). Therefore, the domain is all real numbers and the range is all real numbers greater than or equal to -4.
