Using the Vertical Line Test
In this video, the teacher explains how to use the vertical line test to determine if a graph represents a function or not. They go through four examples and also show how to find a missing value in a table to make it not a function. The...

How does the graph of a function compare to it's inverse
👉 Learn how to find the inverse of a linear function. A linear function is a function whose highest exponent in the variable(s) is 1. The inverse of a function is a function that reverses the "effect" of the original function. One...
