We
{} are used to two types of notation. list one
Set notation
A list
[] mean something specific in set notation. what does it mean?
we include the number next to the [] when graphing (solid dot)
Q: What is constant rate of change?
A: A graph that increases or decreases at a constant rate. This can be for the entire graph, or a small portion of a graph.
A=-1, B=3, C=-2, and D=0 What is 4c-b
5
If y=2x+1, what is the output for the input 2
5
what is a linear relation?
We increase by a linear amount in both the x and u for each increment
A: This type of variable always lie on the y axis, and the depend on another variable to have meaning.
Q: What is a dependent variable?
Are all relations a function and why or why not?
No because some relations have 1 input with 2 outputs
A: This type of relation is a relation what forms a strait line when graphed. An example of this would be y = 3x + 5
Q: What is a linear relation?
A: This type of variable always goes on the x axis. Time and distance are considered examples of this.
Q: What is an independent variable?
f(x) is used in stead of 'y' in specific situations. When we use f(x) what is called?
Function notation
A: this relation is a ________ relation because the equation has one or two variables and it has a degree of 1.
Q: What is a linear relation?
Convert the following set notation into interval notation.
{x| -2 ≤ x ≤ 5, x∈ R}
{y| 100 ≤ y < 260, x∈ R}
D:[-2,5]
R:[100,260)
Are all functions relations, why or why not
Yes, because a relation is a pattern between an x and y which a function will always give.
Simplify 4(x-(-2)
4x+8
A: a pair of numbers who’s order matters. These pairs of numbers use () and are separated by “,” . all elements of this type of set are enclosed in {}.
Q:What is an Ordered Pair?
What does a graph with constant decrease look like compared to a non constant decrease look like?
Show me your work.
Mammals, ice cream flavors, and a bag of your favorite things all considered types of ________.
Discrete variables
Q: Drawing Double: Draw a graph that represents the change in height of a bee.
Q: Drawing Double: Draw a graph that represents a grass hopper jumping in a field of grass.
If the relation rule is f(x)=9x+1, what is the output for the input f(-2)
-17
Graph a function with a domain of [8,16] and a range of [-1,infinity)
check your work
Jimmy tried to write the domain of a graph he was drawing but made two errors. what errors did jimmy make? {x| -6 ≤ x ≤ infinity, x∈ R}
we dont use infinity in interval notation. no domain or range can include infinity.
A: an association between 2 quantities; can be displayed as a table of value, a graph, an equation, arrow diagram or in words
Q: What is a relation?
A line draw in the y direction on a graph is used to check if a graph is a function or not. What is this operation called?
The vertical line test.
Distance ran, elevation change, and number of skittles left in the bowl are all things that can be considered a _______.
Q : What is something we can graph?
