Q. 24 - Precalculus Enhanced with Graphing Utilities

Question

Select a setting so that each given point will lie within the viewing window.

$\left(-80,-60\right),(20,-30),(-20,-40)$

Step-by-Step Solution

Answer

The setting so that each given point lie within the viewing window is  

$$\begin{gathered} X_{min}=-100, \\ X_{max}=-40, \\ {Y}_{min}=-60, \\ {Y}_{max}=80, \\ {X}_{scl}=10 \\ {Y}_{scl}=10 \end{gathered}$$

Step 1 . Given information

The given points are$\left(-80,-60\right),(20,-30),(-20,-40)$

Step 2 . Find the settings for viewig window

By observing given points, 

The minimum value of   is $-80$

The maximum value of  is $20$

The minimum value of  is $-40$

The maximum value of  is $60$

Take each unit on x-axis is $10$

and y-axis is $10.$

Write the setting for the viewing window 

$$\begin{gathered} X_{min}=-100, \\ X_{max}=-40, \\ {Y}_{min}=-60, \\ {Y}_{max}=80, \\ {X}_{scl}=10 \\ {Y}_{scl}=10 \end{gathered}$$
