intrapolation and extrapolation

AAhmed10y ago
What is intrapolation and extrapolation? if the value of x is extrapolation then is it acceptable? Thank you.

If you have 2 values and you approximate for a value between those two values then that is interpolation. If you have 2 values and you approximate for a value outside those two values, then that is extrapolation. Interpolation always gives a better approximation. However usually extrapolation is OK for the exam (although it depends on the question and the topic).
