But how do you come up with a function to fit data? The basic idea is to create a quadratic function and vary the parameters such that the deviation of the actual data from the function is minimized.

Excel's intercept function takes the data points that define a line on a graph and calculates the y value for the point on the graph where x is equal to zero.
