I can identify the domain and range and use them to determine if a relation is a function.
Which relation represents a function?
A. {(1, 2), (2, 3), (3, 2), (4, 3)}
B. {(1, 2), (1, 3), (2, 4), (3, 5)}
A
If f(x)= -3x-2 and g(x)=4x2+4 find f(2)
f(2) = 4
Arizona is the only state where you can stand in four states at once — Utah, Colorado, New Mexico, and this one.
the Four Corners
Identify the domain & range of {(1,5), (2,7), (3,9), (4,7)}
D: 1, 2, 3, 4
R: 5, 7, 9, 7
If f(x)= -3x-2 and g(x)=4x2+4 find f(2)+g(-1)
F(2) = 8
g(-1)= -8
8 + -8 = 0
answer is 0
This city, located in southern Arizona, is known as the “Astronomy Capital of the World.”
Tucson
Find the domain and range of a graph that Ms. Flores shows you
D: x > -2
R: All real numbers
Use the graph that Ms. Flores shows you determine the following: What is f(4)? If f(x)=0, what is x?
f(4) =1
F(-1)=0
This desert covers much of southern Arizona and is known for its giant saguaro cacti.
the Sonoran Desert
This he graph that Ms. Flores shows you a function? Explain in detail.
No because for every input there is NOT only one out put
The cost of riding in an Uber is $1.50 plus $0.35 per mile. This function can be represented as F(x)=0.35x+1.50, where x is the number of miles traveled and F(x) is the cost of the trip.
Using the table that Ms. Flores shows you, determine F(25) AND explain what does F(25) mean in the context of this situation.
f(25)=10.25
meaning when they trawled 25 miles the uber cost is $10.25
The world’s largest stand of Ponderosa pine trees is found near this northern Arizona city.
Flagstaff
Using the table that Ms. Flores shows you, what value could you place in the blank box that would make this relation not a function? Explain why your value works!

The cost of riding in an Uber is $1.50 plus $0.35 per mile. This function can be represented as F(x)=0.35x+1.50, where x is the number of miles traveled and F(x) is the cost of the trip.
If the total cost of your last Uber ride was $14.45, how many miles did you travel?
37 miles
14.45 = .35x+1.50
You can find this colorful, wave-like rock formation near the Arizona-Utah border — but only by lottery permit.
