What is the equation of the parabola?
y= -1/12x^2-2
y=1/12x^2-2
y=-1/12x^2+2
y=1/12x^2+

Step-by-step explanation:

Answer is 1/12x^2 +2

Since the parabola smiles, the coefficient 1/12 should be positive and the constant 2 is positive. The fact that the parabola cuts at positive 2 explains this.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
