Question

What does the equation z = y2 represent?

Answer 1

A parabola

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 2

The equation represents a parabola in the yz-plane. There is no "x" variable or value, therefore it is simply a 2-D parabola.

Since the square (^2) is on the y plane, therefore the parabola is opening with an axis on the y plane.
