Significantly different between two nonlinear functions

Is there any way to find out significantly different between two nonlinear functions?
I have these 2 models for the best fit:
y1 = a1/(b1+x) (blue) and y2 = a2/(b2+x) (red)
Mayby I can log the functions and make it linear and check if the e.g angle are > 0?

Or you could linearise by simply inverting and plotting 1/y1 against x1, and 1/y2 against x2.

Find the errors on the slopes and intercepts. Use them to estimate if the lines are the same to within the errors or not.
