Answer:

y =  {x}^{2}  - 2

Step-by-step explanation:

Find a Rule means write a function for the graph. The graph is shaped like a U so the graph will be a quadratic, so the graph must have a term

{x}^{2}

in it. We are given the vertex of the function. We can use vertex formula

y = (x - h) {}^{2}  + k

where h is the x value of the vertex and k is the y value of the vertex.

y = (x - 0) {}^{2}  - 2

y =  {x}^{2}  - 2

So the rule is

{x}^{2}  - 2
