Fit Curve a Graph with Shape like y^2 = x

I would like to use fit curve for my data that shape like y^2 = x graph (parabola rotated 90° to the right).

I am using custom equation like y=a*sqrt(x+b)+c but y^2 = x does not necessarily mean y=sqrt(x).

How should I change my custom equation?

Thank you.

generally, a function is expected to map only one y value for each x value. As you have two values for each input, you need to redesign your problem. There are two workarounds for this.

You can use two separate equations, that is, and .

Alternately, you can reverse the dependency. That is, use .
