It is a hyperbolic paraboloid! Below is how a mathematician would graph a hyperbolic paraboloid!
Equation: z=Ax2+By2

(where A and B have DIFFERENT signs)

Their official name stems from the fact that their vertical cross sections are parabolas, while the horizontal cross sections are hyperbolas. But even the vertical cross sections are more complicated than with an elliptic paraboloid.
