Is it a Function?
100

True or False-A relation is a set of ordered pairs (a set of inputs and outputs)

What is TRUE?

100
Evaluate f(x)=-3x if x=2
What is -6?
100

Is it a function? Justify your answer. {(2, 3), (4, 5), ( -2, 6)}



Yes, each input has exactly one output.

100
The point (1,2) is in this quadrant
What is the 1st quadrant?
100
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because x does not repeat?
200

The set of first coordinates of a relation or a function (all of the x-values or inputs)

What is Domain?

200
Evaluate f(x)=2x+1 if x=-2
What is -3?
200

Using the vertical line test, does the graph of the points (1,3) and (1,5) represent a function?

No, the points fail the Vertical Line Test.

200
How do you graph the point (-3,4)?
What is you go left 3 units on the x-axis then go up 4 units on the y-axis?
200
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function?
What is False, the points fail the vertical line test
300

The set of second coordinates in a relation or a function (all of the y-values or outputs)

What is the range?

300
Evaluate f(x)=-3 - x if x=6
What is -9?
300

State the domain and range:

xy
37
59
38

D: {3, 5} R: {7, 8, 9}

300
The signs of the points in quadrant 2
What is the (- , +)?
300
Is it a function?
x y
2 4
1 5
2 6
What is NO because x repeats?
400

A relation that assigns exactly one value in the range to each value in the domain?

What is a function?

400

Evaluate f(x)=25 + 4x if x=5

What is 45?

400

Solve for x if

 f(x)=4x+ 25 

AND f(x)=45

What is x=5?

400
The quadrant that doesn't contain one of these points (-2,3), (3,-4) (2,3)
What is the third quadrant?
400
Is it a function?
What is YES because it passes the Vertical Line Test?
500

The test to tell if a graph is a function

What is the Vertical Line Test?

500

Evaluate f(x)=-(4x+2) if x=7

What is -30

500

Solve for x if f(x)=-(4x+2) 

AND

f(x) = -30



What is 7?

500

What quadrant is the point (0,2) in?

What is none because the point sits on the y-axis

500
