200
As x increases and y increases
What is increasing interval
200
a point where the y value is zero
What is a x intercept

What is the domain of a discrete function with the following points: (-1,2), (2, 0), (4, 10), (6, 12)
Domain: {-1, 2, 4, 10, 6}

as x increases and y stays the same
What is constant interval

If f(x)=3x-1 what is f(2)?

How does the vertical line test work? What does it mean to fail? What does it mean to pass?
If the function crosses any vertical line more than once, it fails and it is not a function. If it crosses any vertical line only once or not at all it passes and it is a function!

the point where two functions cross each other, they have the same x and y value at that point.
What is intersection point

Explain the difference between discrete, continuous and discontinuous.
Discrete means the points are not connected (whole number values for x and y). Continuous means all the points are connected so that you can draw the graph without picking up your pencil. Discontinuous means there are sections that are connected but there are parts that are broken off and not connected to each other.
