Function notation minus one exponent?

  • #1
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

[tex]z^{-1} = \frac{1}{z}[/tex]

For instance:

[tex]2^{-1} = \frac{1}{2}[/tex]

Applying this to your problem...
