Unit 1, Functions, Day 3: Representing Domain and Range

Action Items:

1. Turn in Solving Equations Algebra 1 Review Worksheet

2. Turn in Getting to Know You Flashcard (this assignment will begin being docked points for being "late" starting today, but I still want it ASAP!)

3. Finish the Domains and Ranges & Interval Notation Guided Notes (if not finished in class)

4. Finish the Domain and Range Notation Notes Worksheet (due tomorrow)

5. Finish any missing assignments for late credit.

Agenda:

Entry Task: Function Sort Group Practice (Make a list of "Functions" and "Not Functions" by numbers)

Notes:

Guided Notes: Examples of Domains & Ranges from Graphs-1.pdf
Guided Notes: Interval Notation and Domain and Range "Notes" (pages 2 & 3 =Homework)

Unit 1 Outline:

Topics in Introduction to Functions

Guided Notes: Definition of a function (compared to relations) and 4 ways to represent a function
12 Basic Parent Functions:
- Alg 2A: Absolute Value and Polynomial Functions (Constant, Linear, Quadratic, Cubic, Quartic, etc.)
- Note the rest of the basic functions are covered in Alg 2B: Rational, Radical (Square Root, Cube Root), Exponential, Logarithmic]
Sets of Numbers and Number Theory*
Guided Notes: Domain and Range & Interval Notation (we are here!)
Function Notation & Evaluating Functions
Review of Linear Equations
Piecewise and Step Functions
Special Piecewise Function: the Absolute Value Function
Transformations

Foundational Skills: Baseline Expectations and Context

Operations with Numbers and Number Theory*
Solving basic equations (what “show your work” looks like!)
Linear Equations*
Using a graphing calculator

Mathematical Practices:

Making sense of problems and persevere in solving them;
Reasoning abstractly and quantitatively;
Constructing viable arguments and critiquing the reasoning of others;
Modeling with mathematics;
Using appropriate tools strategically;
Attending to precision; and
Looking for and making use of structure (patterns in form and content).

Resources:

Vocabulary: words and ideas you should be comfortable with by the end of Unit 1.
