How can you find x and y intercepts?
Look where they cross the axis or plug in zero for the opposite letter.
State the definition of the domain and range of a function.
The domain is all of the x values of a function.
Range is all of the y values of a function.
What is/are the x-intercept(s) of this function?

(-4,0)
(3,0)
How do you write negative infinity to infinity in set builder notation?
All reals {capital R}
What are the other names for x intercepts?
Solutions, roots and zeros
What is the difference between increasing and decreasing?
Increasing is where the graph is going up. Decreasing is where the graph is going down.
What is the interval of increase for the function below?

Increase: (3, +infinity)
Write in set builder notation: (- inifinty, -2)
x < -2
(0,0)
What is the range of the function graphed below?

Domain: (-infinity, 4]
Does the function below increase from (4,8)

Yes
Write in set builder notation: (-10, 4)
-10 < x < 4
How do you know when a function is positive or negative?
Positive if the y value is greater than zero so above the graph.
Negative if the y value is less than zero or below the graph.
What is the domain of the function graphed below?

Domain: (-infinity, 4]
What is the negative interval of this graph?

(-9, infinity)
Write in set builder notation: (0, infinity)
x > 0
Write the Domain of (-5,6] as an inequality.
-5<x≤6
What is the domain and range of the graph below?

Domain: [-4,3)
Range: (-5,5)
What is the domain, range, increasing, and decreasing of the function below

Domain: All Real Numbers
Range: [-3, + infinity)
Increase: (2, + infinity)
Decrease: (-infinity, -3)
What do the brackets mean when writing in set builder notation: [ 3, 20 ]
Definite pts at 3 and 20. You would write it with and or equal to.
