October 6 - 10
Objective: SWBAT find the inverse of a function from a table, graph, or equation (multirepresentations) TEKS: ALGII.4C
Activities: Warm Up: Composition Functions
Notes: 6.4 Find the inverse of a function (linear, absolute value, cubic, quadratic, ect.) from a
table, graph, equation. Make sure to explain all representations so that students will see the
connection between all multi-representations.
Guided Practice: Students practice finding the inverse of a function with a partner.
