y = -x^2

Step-by-step explanation:

First off you can tell that the graph represents a negative,

nonlinear function due to the direction of the 2 "lines" from

point (0,0). This simply means you can eliminate the graph

representing y = 2x^2 as one of the choices. Now as this is

squared function (^2) you can tell that every x value should be

squared to receive the y value. Here I am suggesting a simple

- x^2 to be defined for the graph.  Take x = 1 as the first

example. If x is squared then y is equal to 1 as well. This is

represented as two coordinates on the graph, when the y value

is negative and when the y value is positive. Now say x = 2.

When x is squared  y = 4, represented by the graph as two

points as well, when y is a negative value of 4 and a positive.

This shows that the graph resembles the function -x^2                             (y = -x^2)

use formula for the circle a=3.14
