The noise level, N, of a sound in decibels is given by: N=f(I) = 10log (I/I0), where I is the intensity of the sound and I0 is a constant. I need to find and interpret f-1(N)
I understand the basis of inverse functions, the output is input, input is output. The inverse undoes the function, etc., I am not sure how to find the inverse. I think it means that the Intensity of sound determines the noise level?
