What does the equation z = y2 represent?

A parabola

Step-by-step explanation:

Remember that quadratic equations on the grap with no other terms are often parabolas in this case the parabola grows in the Z axis amd the y will have two values for every Z value. See the image that is the graph.

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.
