Graphing Functions in Desmos

This lesson demonstrates how to use Desmos to graph functions, adjust the graph window, create and complete a table of values, and find intercepts. It begins with entering equations into Desmos, adjusting the view, and converting equations into tables. The tutorial also covers adding missing values to tables and finding intercepts on the graph, providing a comprehensive guide to using Desmos for graphing and analysis.

What is the first step to start graphing a function in Desmos?

• Use a graphing calculator

• Enter the function directly into the search bar

• Download the Desmos app

• Click on 'Start Graphing' at desmos.com

How can you zoom out on a graph in Desmos?

• Click the minus button

• Click the plus button

• Drag the graph to the left

• Use the scroll wheel on your mouse

What is the purpose of converting an equation to a table in Desmos?

• To export the graph as an image

• To change the color of the graph

• To plot specific points on the graph

• To see the graph in 3D

Which x values are used to complete the table of values for the first equation?

• -2, 0, 2, 4

• 0, 2, 4, 6

• -1, 1, 3, 5

• -3, 0, 3, 6

What is an alternative method to create a table of values in Desmos?

• Manually plotting points on paper

• Using a spreadsheet software

• Using a different graphing tool

• Adding a table item and entering x values

How do you clear the table and corresponding points in Desmos?

• Click the 'Clear All' button

• Delete the equations

• Click the 'X' on the right

• Refresh the page

What are the approximate x-intercepts for the first equation's graph?

• -3.1 and 5.9

• -2.5 and 6.8

• -4.0 and 8.2

• -1.472 and 7.4

What is the y-intercept for the second equation's graph?

• 0, 5

• 0, -2.75

• 0, 1.25

• 0, 3.5

How can you find the intercepts on a graph in Desmos?

• By clicking on the intercept points

• By drawing a line through the origin

• By estimating visually

• By using a calculator

What is the significance of the intercepts in graph analysis?

• They indicate where the graph crosses the axes

• They are used to calculate the area under the curve

• They determine the slope of the graph

• They show the maximum and minimum points
