Piano frequency


There are 52 white keys on a piano.
The frequency of each key is the number of vibrations per second the key's string makes.
Is this relation a function? If not, explain why.
If so, predict an equation that models the data.

Key Position 1 8 15 22 29 36 43
Frequency 27.5 55 110 220 440 880 1760
