Question

How to find value of y in fitting curve linear equation

Answer 1

Answer:

Step-by-step explanation:

If you say the function is similar to a quadratic, it should look like:

f(x) = ax² + bx + c

Hence you can just fit your curve with a program of your choice (that can be done in ORIGIN, EXCELL, ...).

c is very easy to obtain, it is just the point where your curve intersects the y-axis.

b is the inclinitation of your function on the point where it intersects the y-axis and

the sign of a shows you the direction of your quadratic, so if

a > 0 the parabola opening points upward or if

a < 0 the parabola opening points downward.
