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 Show moreIn this section, we will explore the inverses of polynomial and rational functions and in particular the radical functions we encounter in the process.

(9.3.1) – Evaluating Radical functions. (9.3.2) – Finding the domain of a radical function. In this section we will extend our previous work with functions to include radicals. If a function is defined by a radical expression, we call it a radical function. The square root function is f (x) =√x f ( x) = x.The inverse of a quadratic function is a square root function. Both are toolkit functions and different types of power functions. Functions involving roots are often called radical functions. While it is not possible to find an inverse of most polynomial functions, some basic polynomials do have inverses.sin 𝜃 cos 𝜃 = 1/3. We can write this as: sin 2𝜃 = 2/3. To solve for 𝜃, we must first take the arcsine or inverse sine of both sides. The arcsine function is the inverse of the sine function: 2𝜃 = arcsin (2/3) 𝜃 = (1/2)arcsin (2/3) This is just one practical example of using an inverse function.
