True or False - A function can be written as a graph, coordinates, an X/Y table, or a function map.
What is TRUE?
Is it a function? {(2, 3), (4, 5), ( -2, 6)}
What is YES because every input has one output?
y = 8 - x2
What is nonlinear?
The set of first coordinates of a relation or a function
What is Domain?
How do you graph the point (-3,4)?
What is go left 3 units on the x-axis then go up 4 units on the y-axis?
Using the vertical line test does the graph of the points (1,3) and (1,5) represent a function?
What is NO, the points fail the vertical line test
Linear or nonlinear?
What is LINEAR?
The signs of any point in quadrant 2 (written as a set of coordinates)
What is the (- , +)?
Is it a function?
| x | y |
| 2 | 4 |
| 1 | 5 |
| 2 | 6 |
What is NO because x repeats?
y = 3x - 9
What is LINEAR?
The quadrant that doesn't contain one of these points (-2,3), (3,-4) (2,3)
What is the third quadrant?
Is it a function? 
What is NO because it does not pass the Vertical Line Test?
{ (-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}
What is NONLINEAR?
{(2, 4), (6, 8), (9, 4), (-9, 6), (10, 14), (15, 14)}
What is YES it is a function?
{(0,0), (1, 20), (2, 40), (3, 60), (4, 80)}
