Given n+1 data points , and assume you pass a function f(x) through all the data points.  If now the value of the function f(x) is required to be found outside the range of given x-data, the procedure is called

extrapolation
interpolation
guessing

regression

Given three data points (1,6), (3,28), (10, 231), it is found that the function y=2x²+3x+1 passes through all the three data points.  Your estimate of y at x=2 is
