Functions: Domain, Range, End Behavior, Increasing or Decreasing Reporting Category Functions Topic Finding domain and range; determining whether a function is increasing or decreasing Primary SOL AII.7 The student will investigate and analyze functions algebraically and graphically. Key concepts include.
EXAMPLES OF DOMAINS AND RANGES FROM GRAPHS Important notes about Domains and Ranges from Graphs: Remember that domain refers to the x-values that are represented in a problem and range refers to the y-values that are represented in a problem. Sometimes it isn’t possible to list all the values that x or y can be because the graph.
So that's its range. Let's do a few more. This is kind of fun. The function f of x is graphed. What is its domain? So once again, this function is defined for negative 2. Negative 2 is less than or equal to x, which is less than or equal to 5. If you give me an x anywhere in between negative 2 and 5, I can look at this graph to see where the function is defined. f of negative 2 is negative 4.
What kind of function do you find slope for? We only find slope for linear functions The slope of a line does not change no matter where you find it on the line. This is called constant rate of change What do we do for other types of functions? Find the average rate of change in a specific interval.

Domain and Range. x-intercepts and y-intercepts. Positive and Negative intervals. Intervals of increasing, decreasing and constant behavior. Parent Functions. Maxima and Minima; Domain and Range. Domain: The domain is the set of all possible inputs or x-values. To find the domain of a function, we have to look at the x-axis of the graph.
