In this lesson, you will learn about linear approximation with interpolation. You will understand that any relationship can be modeled linearly if one restricts the domain enough, and how to do linear interpolation to get a quick estimate of the value of the relationship between two points. You will also see how linear interpolation works with a table of input and output values for a relationship, and how to make a new table with interpolated values. This skill will come in handy when you need to estimate an output for an input beyond the data.
Understand clearly that ANY relationship can be modeled linearly if one restricts the domain enough.
