Step 1 Find a model that fits the data You should come up with an equation in the form y = Abx.
y=1.06b^x
Step 2 Use your model to find the frequency of the note two octaves above middle C (note 24).
1026
Step 3 Find the note with a frequency of 600. (How?)
note 15
Umm. that's very pretty, but you didn't answer the questions that were asked. Please revise.
