Data Age 2 To 20 And Bmi How Do I Find The Function That Describes My Data/plotted Graph?

How do I find the function that describes my data/plotted graph? - data age 2 to 20 and bmi

Then he gave me a set of data: shows the body mass index of the U.S. average for women 2-20. How do I find a function (without using the regression tool) into my computer, that part of the graph is generated by plotting the data? And what does it mean when you made the "state variables and parameters?

I am very confused, please help: (

... Finite-difference could be used to find a polynomial - but certainly not exactly match the data with a polynomial must use a test ... could also be a single line most appropriate in this case, after the data pull away, the line and write the equation ...

scored two points on the graph. (while on the line / curve)
For example, (2.5) and (3.2)

Find the slope of the straight line

by the following equation:
Y2-Y1
-------- = Use the course of two points and the entry into this
X1-X2 of Eq. SO (2.5) = (x1, y1)
and 2 is the x-cordinated
and 5 is the y-cordinated
SO (3.2) = (x2, y2)
as in the above equation to the slope

then u is the slope. be represented by an "M"
Use x1 and y1 and "m" (gradient) provided in this equation, the function of youre online
y-y1 = m (x-x1)
So for my example:
Y-5 = m (x-2)
(Then type the value of m). youre simplify the equation by expanding the brackets. Then place theEquation set up:
y = ax + c
where A and C are numbers that
