Janna is making a prediction of the frequency of a key that is 12 keys from middle c.
a 2-column table with 5 rows. the first column is labeled number of keys above middle c with entries 0, 1, 2, 4, 8. the second column is labeled frequency (hertz) with entries 277.18, 293.66, 311.13, 249.23, 440.00.
which best describes her prediction?
interpolation, because a key that is 12 keys from middle c is within the data set
interpolation, because a key that is 12 keys from middle c is outside the data set
extrapolation, because a key that is 12 keys from middle c is within the data set
extrapolation, because a key that is 12 keys from middle c is outside the data set
