Function notation minus one exponent?

Click For Summary
SUMMARY

The discussion clarifies the meaning of function notation with a negative exponent, specifically in the context of the logistic function. The notation f(x) = f0[1 + exp(−βx)]^-1 indicates that the function is expressed as the reciprocal of the term inside the brackets. This is exemplified by the mathematical expression 2^{-1} = 1/2, demonstrating that a negative exponent signifies the inverse of the base.

Hi !

What does the notation mean exactly when a function has power minus one ?

For example i have seen the logistic function written as:

f(x) = f0[1 + exp(−βx)]^-1
 
Mathematics news on Phys.org
z^{-1} = \frac{1}{z}

For instance:

2^{-1} = \frac{1}{2}

Applying this to your problem...
 
oh ok, thanks 4 the help.
