Representing Mathematical Relationships with Equations and Graphs

The video tutorial covers two examples of representing mathematical relationships using equations, tables, and graphs. The first example involves calculating the remaining vegetable oil after baking a certain number of cakes, using an equation and representing the data in a table and graph. The second example models the ascent of a submarine from 45 feet below the water surface, using an equation to calculate depth over time and graphing the results. Both examples demonstrate how different representations can tell the same story.

What are the different ways of representing relationships in math mentioned in the video?

• Words, equations, tables, and graphs

• Numbers, shapes, colors, and sizes

• Letters, symbols, diagrams, and charts

• Pictures, stories, songs, and dances
