To calculate the inverse of a function, swap the x and y variables then solve for y in terms of x.
What are the 3 methods for finding the inverse of a function?
There are 3 methods for finding the inverse of a function: algebraic method, graphical method, and numerical method.
What is the inverse of a function?
The inverse of a function f is a function f^(-1) such that, for all x in the domain of f, f^(-1)(f(x)) = x. Similarly, for all y in the domain of f^(-1), f(f^(-1)(y)) = y
Can you always find the inverse of a function?
Not every function has an inverse. A function can only have an inverse if it is one-to-one so that no two elements in the domain are matched to the same element in the range. A non-one-to-one function is not invertible.
