This document provides an overview of lessons on functions and function notation for algebra students. It includes the class rules, mission and vision statements for the Georgia Cyber Academy, and various exercises on function domains, interval notation, and graphing functions. Students are instructed to complete online lessons on functions and function notation, and can attend a help session for any questions.

Lesson 1.06:
Function
Notation
Lesson 1.07: Functions
Do you have your
math notebook,
calculator, and
something to write
with?
1.07 SI 2s
“With flexibility comes responsibility.”

2. * Class Rules *
- Be Active
- Be Polite
- Be Courteous
- Be Respectful
MISSION: The mission of the Georgia Cyber Academy is to provide an
exemplary individualized and engaging educational experience for all
students by incorporating school and community/family partnerships
coupled with a rigorous curriculum within a data-driven and studentcentered instructional model. Student success will be measured by valid
and reliable assessment data, parent and student satisfaction, and
continued institutional growth within the academic community.
VISION: GCA students will emerge as confident leaders in the 21st century
global community through a holistic approach of rigorous academic
standards, a commitment to individualized learning paths, and attention to
the growth of each student as a civic minded contributor both within their
local communities and beyond.

3. This week a lot is happening! Stay on top of things!

4. Does your SI look like this?
Or this?

5. CCGPS Standards
GA.MCC9-12.F.IF.5
Relate the domain of a function to its graph
and, where applicable, to the quantitative
relationship it describes, For example, if the
function h(n) gives the number of personhours it takes to assemble n engines in a
factory, then the positive integers would be an
appropriate domain for the function.

6. Review
1. Write the equation to this
line in function notation.
2. What is the domain of this
function? How could we
write this?

7. Interval Notation
In “Interval Notation” you just write the beginning
and ending numbers of the interval, and use:
[ ] a square bracket if you want to include the
value, or
( ) a round bracket if you do NOT want to include
the value

8. Old way:
0<x≤20
New way:

9. Domain and Interval Notation
Rewrite these domains in interval notation:
1.-2<x<4
2. -∞< x≤ 6

10. Domain and Interval Notation.
Now let’s look at a graph. What is the
domain? Write the domain in interval
notation.
Does it extend forever and ever in both directions? What will my two
end numbers be?

11. We ♥ MATH! So what is the DOMAIN on the
function in the interval between the 2 ♥’s.

12. Lets look at one in context…

14. Study Island 2s
What do you think this graph would look like? Think about what “t”
represents.

16. Study Island 2s

18. Can you eat
negative
hamburgers?

20. Think about what
the domain or
input, or x-values
represent. What
type of constraint
must we have?

22. Let’s look at some
exponential
functions!

24. What does this graph
look like? Let’s look at
this cool website!

27. Use the graphing website to help
you visualize the graph!
