1. SWBAT FIND INVERSE FUNCTIONS 6.4 INVERSE FUNCTIONS

3. **Inverse Relation** interchanges the outputs and the input values. This means the domain and range are also interchanged. x 1 2 3 4 5 y 9 12 18 15 2 The inverse of the above relation, would be: x 9 12 18 15 2 y 1 2 3 4 5

4. A **Graph of the Inverse of a relation** is a reflection of the graph of the original relation. The line of reflection is y = x. (6, 3). The inverse is (3, 6) (7, -2), inverse is (-2, 7) (-4, -6), inverse is (-6, -4) A point and it’s inverse, when connected with a line, the line will be perpendicular to the line y = x.

8. Find the inverse of the model. Use the inverse function to find the number of greeting cards produced in a month in which the company’s total to produce the cards was $615.

9. Horizontal Line Test! The inverse of a function f is also a function IF AND ONLY IF no horizontal line intersects the graph of f more than once!
