Discrete Scenarios in Graphs

The scenarios where the height of a student depending on age, time taken in a race depending on distance, number of students taking a test depending on class size, and length of a walkway depending on number of bricks are analyzed to determine which would result in a discrete graph with isolated points. The concept of discrete data with whole numbers only is explained within these scenarios.

1. 9/28 9/28: Warm : Warm Up The graph of which of following scenarios would be discrete? Up Monday Monday Discrete means isolated points (cannot be points in between; whole numbers only: no fractions or decimals) A The height h, in inches, of a student depends on the student s age, a, in years. B The time t, in seconds, it takes a runner to finish a race depends on the distance in miles m of the race. C The number of students taking a test n depends on the number of students in the class c. D The length l, in feet, of a walkway depends on the number of bricks b used.

2. 9/28 Objective 9/28 Objective I will be able to identify and represent patterns that describe linear functions.
