Is it a Function?
Linear or Nonlinear?
100
True or False-A function can be written as a graph, coordinates, an X/Y table, or a function map.
What is TRUE?
100
Evaluate f(x)=-3x if x=2
What is -6?
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?
100
y = 8 - x2
What is NONLINEAR?
200
The set of all x coordinates of a function
What is Domain?
200
Evaluate f(x)=2x+1 if x=-2
What is -3?
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
200
Is it linear or nonlinear?
What is LINEAR?
300
The set of all y coordinates in a function
What is the range?
300
Evaluate f(x)=-3 - x if x=6
What is -9?
300
The signs of the points in quadrant 2 (written as a set of coordinates)
What is the (- , +)?
300
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
300
y = 3x - 9
What is LINEAR?
400
A relation that assigns exactly one output to every input.
What is a function?
400
Evaluate f(x)=25 + 4x if x=5
What is 45?
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 NO because it does not pass the Vertical Line Test?
400
{ (-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}
What is NONLINEAR?
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
What quadrant is the point (0,2) in?
What is none because the point sits on the y-axis
500
{(2, 4), (6, 8), (9, 4), (-9, 6), (10, 14), (15, 14)}
What is YES it is a function
500
{(0,0), (1, 20), (2, 40), (3, 60), (4, 80)}
What is LINEAR?
