Question

If you wanted to predict the value of the y variable when the x variable is 15, you would be _____ the data.

Answer 1

Extrapolation is the process by which a value is estimated by using a previously known set of numbers. Interpolation is where a value is estimated between two known values. In this case, if you wanted to predict the value of the y-variable when the x-variable is 15, you would be extrapolating beyond the known data-set. 

Answer 2

Answer:

Extrapolating

Step-by-step explanation:

In math we can define extrapolation as the process of estimating a value that is beyond our range of observation and if we look at the graph we can observe that the $x$ variable only has matcihng values with $y$ up until $9$. We want to predict the value of the $y$ variable when $x$ is $15$ and this is outside the range of observation.
