It is possible to prove that for f(x):
However we can see that this not true for g(x), which is a linear equation with a small shift:
An inverse equation has different properties to a linear equation
Since,
The left hand side needs to be multiplied by (x+y) in order to equal the right hand side therefore:
Logarithmic functions have the characteristic that adding two logs together is the same as multiplication of the variables:
Exponential functions have the characteristic that multiplying to exponentials together is the same as addition for the variables:
