But general equation of parabola is Y = A + BX^2

[@itiscivilengineeringcivilelite]

There are three equations for fitting a quadratic curve.
One which I have solved in this video.
Other two are y = a + bx²
And y = ax + bx²
You can fit a curve for y = a + bx²
by same method as shown in this video.
But the normal equations for your case will be:
sigma y = na + b (sigma x²)
and
sigma x²y = a (sigma x²) + b (sigma x^4)
And then you will to solve the equation for two unknowns.
Hope it is clear to you!
