Use the diagram to write the standard equation of the circle. a: x^2 + y^2 = 9 b: x^2 + y^2 = 16 c: x^2 + y^2 = 18 d: x^2 + y^2 = 4

40 is the final : )

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.
