Unformatted text preview: A one-to-one function is a function where each value of the dependent variable is assigned to exactly one value of the independent variable. Determining one-to-one functions graphically: use horizontal line test. How to nd inverse functions: 1. Numerically: 2. Graphically: 3. Algebraically: (a) Write y = f ( x ) (b) Interchange x and y . (c) Solve for y in terms of x (d) Write y as f-1 ( x ) Examples: Find the inverse function for each of the following functions: 1. g ( x ) = 3-x 4 2. h ( x ) =-5 x + 1 x-1...
