# Interactive video lesson plan for: Composite Functions Domain Fractions & Square Roots / Radicals - Inverse Functions & Graphs

#### Activity overview:

This algebra 2 and precalculus video tutorial provides an introduction basic overview / review on composite functions that contain fractions and radicals such as square root functions. It explains how to find the domain of a composition of functions and how to express it using interval notation and a number line. It also shows you how to determine if two functions are inverses of each other. This video contains plenty of examples and practice problems.

Here is a list of topics:
1. Composition of Functions - (f o g)(x), f(g(x)), and g(f(x))
2. Composite Functions With Square Roots - Finding the Domain
3. Radical Functions & Inequalities - Using Number Lines & Interval Notation
4. Composition Functions With Fractions - No Zero in the Denominator - Undefined Situation
5. Input and Output Functions - f(x) and g(x)
6. Open vs Closed Circles on Number Lines
7. Brackets vs Parentheses - Domain & Interval Notation
8. All real number situations
9. How to find the inverse of f(x)
10. How to determine if two functions are inverses of each other
11. reflection over line y=x, inverse function f^-1(x)
12. composition of functions - algebra 2 and precalculus
13. graphing the inverse function,

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

@strykerstennis

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
