How to Determine the Inverse of Functions
In mathematics, every function has two components: the function itself and its inverse. The inverse function reverses all the actions performed by the function. The inverse of a function uses the output solution to arrive back at the origin... Read More »

How to Find the Inverse of a Function
The inverse of a function is simply the exact opposite or negative of a mathematical function or equation relating x to y. The calculation is simple. If given y, solve for x or vice versa. Read More »

The inverse of a value is the number 1 divided by that value. The inverse of a function is 1 divided by that entire function or that function raised to the power of -1. The inverse of "y = x," for instance, is "y = 1/x," and the inverse of ...

Replace f(x) with 'y'. f(x) is the same as 'y'. This step is done because f(x) is bulky while 'y' is more simple/easier to work with. 2. SWITCH 'x' and 'y'. This means that everywhere you have an 'x', replace it with 'y', and everywhere you...

The logarithm function. If y = b x , then x = b y is the inverse --> y = log b (x). If b = 10, then the function is often stated with the '10' implied: just log(x). For natural logarithms (y = e x ), the function y = ln(x) [which indicates ...
