1 Family Functions – Discrete vs. Continuous

2 Discrete A discrete function/graph only consists of certain distinct points – points that can be counted or listed. For instance, the number of students in my classes throughout the day is a discrete function (can’t have half of a student).

3 Continuous A continuous function/graph consists of all points within a given interval (including up to infinity). For instance, the height of students in my classes throughout the day is a continuous function (can have decimal answers). Another way to think of continuous is “did I have to pick up my pencil in the drawing of the graph?

4 Discrete or Continuous? Neither!

5 Neither We can also have “neither” discrete or continuous. –This occurs when our graph “jumps” points which makes it not continuous, but has possible decimal values, which makes is not discrete.

6 Classify Each Graph Discrete Continuous

7 Intercepts Where the graph crosses the axis. –x-intercept: where the graph crosses the x- axis. –y-intercept: where the graph crosses the y- intercept. y = 0 x = 0
