Question

f(x)= 2x + 8 if x < 1
-3x + 7 if 1 ≤ x < 3
√x-3 if x ≥ 3

Answer 1

What do you want to do here?

Answer 2

Graph it using graphing technology

Answer 3

what graphing devices do you have available?

Answer 4

geogebra

Answer 5

ok one sec

Answer 6

Okay, Thankyou !

Answer 7

To graph this, you basically graph each piece separately

You make sure that only a part of each piece is graph (the correct part)

So for instance, you only want to graph 2x + 8 only when x < 1

So you type in

function[2x+8, -1000,1]

---------------------------------

To graph y = -3x + 7 for 1 ≤ x < 3, you type

function[-3x + 7, 1,3]

---------------------------------

To graph y = √x-3 for x ≥ 3, you type

function[√x-3 , 3,1000]

Note: I'm assuming only the x is in the square root

Doing all this gives you what you see as attached

Note: I changed the color so you can see each piece individually

Answer 8

The red piece is the first piece

The blue piece is the second piece

The green piece is the third piece

Keep in mind where the open and closed circles are
