Question

janna is making a prediction of the frequency of a key that is 12 keys from middle c.

sound frequencies (piano)

\

$$\begin{tabular}{|c|c|} \\hline \\text{number of keys above middle c} & \\text{frequency (hz)} \\\\ \\hline 0 & 277.18 \\\\ \\hline 1 & 293.66 \\\\ \\hline 2 & 311.13 \\\\ \\hline 4 & 349.23 \\\\ \\hline 8 & 440.00 \\\\ \\hline \\end{tabular}$$

which best describes her prediction?

\bigcirc interpolation, because a key that is 12 keys from middle c is within the data set
\bigcirc interpolation, because a key that is 12 keys from middle c is outside the data set
\bigcirc extrapolation, because a key that is 12 keys from middle c is within the data set
\bigcirc extrapolation, because a key that is 12 keys from middle c is outside the data set

Identify the range of the given data set

The independent variable is the "Number of keys above middle C". The values provided in the table are \(0, 1, 2, 4,\) and \(8\). Thus, the domain of the given data set ranges from \(0\) to \(8\).

Analyze the prediction value

Janna is making a prediction for a key that is \(12\) keys from middle C. The value \(12\) lies outside the interval of the observed data, which is \([0, 8]\).

Determine interpolation vs. extrapolation

Making a prediction outside the range of the observed data set is defined as extrapolation. Since \(12 > 8\), this prediction is an extrapolation because the value is outside the data set.
