Generating the function from given coordinates and slopes

  1. Jun 24, 2014 #1
    hi fellas, i have been given a graph from which i can extract the coordinates and the slopes but all i need is to generate the function this graph represents. can you suggest me any manual procedure to do this mathematically or do i have to use software to generate polynomial functions?
    if there is any useful software to generate functions from co ordinates please let me know

    Do you have any ideas, suspicions etc as to what sort of function it is - polynomial, trigonometric, exponential...
    Without that one could work out a function that fits the values and slopes but it wouldn't necessarily produce correct values for other points.

    i got the curve to be sort of a straight line. I might have worked out with it to get a y=mx curve, but i m looking for a more accurate function because my straight line is slightly deviating from its path, not exponential though..actually i need to know if there is any mathematical manual process to get the accurate function or if you can suggest me a software which does it?

    Excel has a curve fitting function.
