To practice writing the equations of horizontal parabolas, write the equations of these two parabolas in vertex form: focus at (4, 3), and directrix x = 2

focus at (2, -1), and directrix x = 8​

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.
