Function rules
what makes a set of ordered pairs a function?
When the x value does not repeat
what is the x-axis and what is the y-axis
x- horizontal
y- vertical
does this set of ordered pairs represent a funciton-
{(2,4), (5,9), (8,2)}
yes
what is the vertical line test?
where you can draw a straight line through the graph
what is my husbands name
Bo
make a table with 4 ordered pairs for this function
y = 3x - 5
see tables
draw a Cartesian plane and label the quadrants
*look at pictures*
state the independent and dependent variable-
"graphing the ages and heights of students in a nutritional study"
age (independent): height (dependent)
is the relation y = 3 a function and what would the graph look like
yes, straight line
what are my kids names
Noa and Scottie
write a function rule for this set of ordered pairs
{(-2,1), (0, 0), (2, -1), (4, -2), (6, -3)
f(x) = -1/2x
graph this relation and state whether it is a function
y = 2x - 4 and x = 0, 2, 5

{(6,10), (-9,14), (4,2), (-9,8)}
D= -9, 4, 6
R= 2, 8, 10, 14
what does an absolute value graph look like?
V shape
I teach and own my own business. What is the business for?
charcuterie /grazing tables
what is the function rule for this set of ordered pairs
{(-2, -8), (-1, -5), (0, -2), (1, 1), (2, 4)
f(x) = 3x - 2
sketch a graph of a man's heart rate over the course of an hour in which he mows the lawn with a push mower for 20 min, rests for 15 mins, lifts weights for 10 mins, and then reads for the rest of the hour

given f= {(1,2), (3,5), (8,9), (2, 10)}
f(2) =
10
draw a mapping diagram and state whether it is a function
{(-5,1), (-5,2), (2,8), (5,6)}
no not a function
