### Proof: Invertibility implies a unique solution to f(x)=y

In mathematics, an

**inverse function**is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa. i.e.,*f*(*x*) =*y*if and only if*g*(*y*) =*x*. Referred from Wikipedia.**Proof: Invertibility implies a unique solution to f(x)=y**: Proof: Invertibility implies a unique solution to f(x)=y for all y in co-domain of f.

### Dependent and independent variables

For p=5q

p is dependent on what happens to q so p is the dependent variable.

p is dependent on what happens to q so p is the dependent variable.

**Dependent and independent variables exercise: the basics**: Here we have a problem that asks us to identify which variables are dependent and independent. Hint: independent variables are not influenced and remain unchanged by the other variable.## Wednesday, August 27, 2014
