Tips and Tricks

Think "SAME"

Type the original in Desmos

Check each answer to see what is the same!

*Change all letters to "x"*

"equivalent" or "best represents"

Think same x-intercept

Type the original in Desmos

Check each answer to see which crosses the same x-intercept as the original!

*Change all letters to "x"*

"is a factor"

Domain: think x-values, left to right
#<x<#

Range: think y-values, bottom to top
#<y<#

"domain" and/or "range"

Open circle: < >
Closed circle: ≤ ≥

Arrow left/down: -∞
x<# or y<#

Arrow right/up: ∞
x># or y>#

Type each answer and create a table

The tables must be the same!

table and equations?

Make a table
Use linear regression



m= slope or rate of change
b= y-intercept
*check the answers to see what is the same

slope from a table or points?

Key Features

"solution" or "makes the equation true"

Think "intersection"

Type one side in Desmos Line 1
Type the other side in Desmos Line 2

Find where the two lines cross: (#, #) or (x, y)
The answer is usually the x-value.



*Change all letters to "x"*

"value"

Think "number"

Type the function in Desmos Line 1
Type the other function in Desmos Line 2
