Based on the data in the table, which function models the frequency, y, in waves per second, of sound waves with a wavelength of x meters?

A. y= 340x

B. y= x/340

C. y= 340x

D. y= 340/x

D. y = 340/x

Step-by-step explanation:

To start off take the first y and subtract it by the second y.

680 - 340 = 340

Then do the same with the second y and the third y.

340 - 227 = 133

Here you see that it is decreasing so you can automatically cancel out A and C as and answer.

Now you have the choice for B or D

The answer would be D because the answer still comes out as a whole number, as for B would make the answer a decimal.
