Question

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

correlating
extrapolating
interpolating

Answer 1

Extrapolating

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.

Answer 2

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.
