2. 5.1 Linear Functions and Graphs
RECALL from chapter 1 problems where they asked you to complete a
table of values for x = 1, 2, 3, 4, 5 for y = 4x - 3
What did you do?
This concept is broadened in this chapter--
THIS IS THE MOST IMPORTANT CHAPTER IN THE BOOK!!!
You need to know how to graph lines and interpret them.
This will be in chapter 6 and chapter 7 and chapter 10.
IT WILL BE USED IN GEOMETRY and ALGBERA 2 and ON THE
SAT and the PSSA
3. THIS section is relatively easy.
The whole point is to understand what a function is.
Let's first start with relations:
A relation is a set of numbers, like an ordered pair. It is a
function if the FIRST number is paired with one and only
one second number?
