Image 1 Caption: An example set of power-law curves.

Feattures:

1. The power-law formula is:

   f(x) = Ax^p ,

   where A is a constant and p is the power (AKA exponent).

2. The set of power-law curves has A = 1 and p = 1, 2, 3, 4.

   

3. Image 2 Caption: Another example set of power-law curves now with A = 1 and p = ±1, ±2, ±3, ±4.

   The curves with negative powers are inverse power laws have infinities at zero

4. Keywords: constant, infinity (∞), inverse proportionality, inverse-square law, plus-minus sign ±, power (AKA exponent), power law (AKA scaling law), proportionality, zero (0), etc.
