Which of these tables could represent a quadratic function?

, i need to pass this test.

Aquadratic function has the general form of equation written as: y = ax² + bx + c. when you graph this equation, it would give a characteristic of a parabolic form. this curve forms like a symmetric arc. the solution is to plot the points to a graph as shown in the picture attached. as you can see, only the last graph shows a parabolic curve. thus, this points represent a quadratic function. the answer is the last table in the choices.
