Describe what the x and y intercepts are and how to find them
where the graph crosses the x axis, where the graph crosses the Y axis
Describe the min and max
Where the graph changes direction, the hill/valley of the graph, etc.
Describe interval of increase and interval of decrease
Interval of increase: Where the "roller coaster" is going up, where the slope is positive
Interval of decrease: Where the "roller coaster" is going down, where the slope is negative
Describe the positive and negative interval
Positive interval: Where graph is above the x axis
Negative interval: where graph is below the x axis
Describe end behavior
Looking at if the y numbers will be increasing or decreasing as x increases and decreases.
