The rectangle below has an area of 4(x+3) [4 is width, x+3 is length] square units. if the dimensions of the rectangle are doubled, what is the area of the new rectangle in terms of x?

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

is only a line? i think so
