It is not a function.

Step-by-step explanation:

To check whether if the graph is a function or not, you can do by drawing a straight verticle line.

If the line and the graph have more than one common point (Basically if the line intersects the graph more than one point) then that graph is not a function.If the line and the graph have only one common point (Basically if the line intersects the graph only one point) then it is a function.

When we draw a vertical line, passing through the graph, we notice that both have more than one common point.

Hence, the graph is not a function.

Facts!

The graph is called Parabola.It is mostly appeared in Conic Section.Assuming from the graph, the equation for this parabola is y^2 = x.Any equations that have 'y^2' will not be a function as y^2 gives more than one output value.
