Ways to tell them apart:
Remember that inter means between, so interpolate relates to working within a known range.
In contrast, extra suggests beyond, indicating extrapolate is about extending beyond known points.
Interpolate is like filling gaps in data, while extrapolate is projecting data into the unknown.
Interpolate deals with interior data points, whereas extrapolate deals with exterior points.
Interpolate is safer with known conditions; extrapolate ventures into the realm of prediction.
