The Plan For Today

HWQ #6 – Fri. 10/9

Quiz: Module 3 – Mon. 10/12

Lesson 3.1 – Graphing Relationships

A person decides to go for a run but must take breaks at certain points. The person’s distance

from the house is shown in the graph.

Lesson 3.1 – Graphing Relationships

You and a friend are playing catch. You throw three different balls to your friend.

A. You throw the first ball in an arc and your friend catches it.

B. You throw the second ball in an arc, but this time the ball gets stuck in a tree.

C. You throw the third ball directly at your friend, but it lands in front of your friend, and rolls the rest of the way on the ground.

The three graphs of these situations are shown.

Lesson 3.1 – Graphing Relationships

Some graphs that represent real-world situations are drawn without any interruptions. In other words, they are

continuous graphs. A continuous graph is a graph that is made up of connected lines or curves. For example, the graph that represents the distance of a delivery truck from a

warehouse consists of line segments without any interruptions, so it is an example of a continuous graph.

Other types of graphs are not continuous. They are made up of distinct, unconnected points. These graphs are called

discrete graphs. These types of graphs are drawn when multiple points or data are given and you want to find a trend in the data or when it does not make sense to connect

the points.

Lesson 3.1 – Graphing Relationships

When sketching or interpreting a graph, pay close attention to the labels on each axis.

Helpful Hint

Both graphs show a relationship about a child going down a slide. Graph A represents the child’s distance from the ground related

to time. Graph B represents the child’s Speed related to time.

Lesson 3.1 – Graphing Relationships

The domain of a relation is the set of x-values.

The range of a relation is the set of y-values.

Could be an inequality or a list depending on the type of graph and the data.
