What is the extrapolation in graph?

Answer:

Given x,y data are plotted on a graph and a trend to the data is identified (usually using regression), to extrapolate the data is to estimate y values beyond the known range, as shown on the x axis, of the data.

In a more general sense, with multiple independent variables, an extrapolation would be going outside the known ranges of any of the independent variables in the prediction of the dependent variable.
