1 Unit 1: Functions Minds On

2 Unit 1: Functions Lesson 5: Inverse Functions Example: Find the inverse of f(x) = (x – 3) 2 + 5

3 Unit 1: Functions Lesson 5: Inverse Functions To find the inverse of a quadratic function in standard form, complete the square to put it in vertex form Ex. Find the inverse of: f(x) = 2x 2 + 16x + 24

4 Unit 1: Functions Lesson 5: Inverse Functions

5 Unit 1: Functions Lesson 5: Inverse Functions The inverse of a quadratic is NOT a function. We can make it a function by restricting the domain. Determine the inverse of f(x) = (x – 2) 2 – 4. Is it a function?
