Sophia: Determining an Inverse Function Value From a Trig Table

Young mathematicians look for patterns in inverse functions as they relate to the original functions. The comprehensive lesson emphasizes vocabulary throughout as well as algebraic and graphical characteristics of the inverse functions.

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts with an intuitive sense of what a function inverse is. Using an example, he then shows how to find the inverse of a function and how the graph of...

This video explains how to determine function values and inverse function values using the graph of a function. [4:23]

Is the inverse a function? Scholars learn how to examine a function to answer this question. Using an online interactive, they examine the properties of inverse functions to compare to the original function.

The opposite operations in the opposite order create the inverse of a function. A video demonstration explains the algebraic steps in creating inverse functions from different types of functions. The examples include linear, rational,...

Offers a step-by-step explanation of a one-to-one function problem on inverse functions with restricted domains, clearly using the horizontal line test. Includes sample problems.
