What is predicting y for a value of x that is within the interval of p

1.	What is predicting y for a value of x that is within the interval of points that we saw in the original data called?(a) Regression(b) Extrapolation(c) Intra polation(d) PolationThe question was posed to me at a job interview.I need to ask this question from Linear Regression topic in chapter Commands, Packages, Visualizing Data and Linear Regression of R Programming
Answer» CORRECT answer is (c) Intra polation For EXPLANATION I would say: Predicting y for a value of x that is within the interval of points that we SAW in the original DATA is called interpolation. Predicting y for a value of x that’s OUTSIDE the range of values we actually saw for x in the original data is called extrapolation.
