Answer 5

@FortyTheRapper

Answer 6

I know the graph should be like this,

Answer 7

For the first one, it says x = -4

So wherever you see a x in the original equation, you replace it with a -4

For the first one: \[y = \left| (-4)+2 \right| -1

See how it is basically the same equation, we just plugged in the given x value instead of writing x itself?

Answer 8

\[y = \left| (-4)+2 \right|-1\]

Answer 9

Oh! So like in the second column I would write; (-3)+2 -1 ?

Answer 10

Exactly!
Just remember the absolute value bars and you're good to go

Answer 11

Okay, gimme 1 sec to write this down, and after, do you mind checking if I filled it in correctly?

Answer 12

Sure, I dont mind

Answer 13

How do I fill in the y, and (x,y) columns?

Answer 14

(x,y) -- those are the values that you have on your graph. You can just copy those

And remember to turn those parenthesis into straight lines. Those make a big difference in calculations

Answer 15

Alright, just to be sure, is this how it should look?

Answer 16

@FortyTheRapper You there?

Answer 17

Oh yeah, I'm here mb. I'm working on some Physics myself

And yep, its good! Just remember to add a "-1" in the equation part for x = -1

\[y = \left| (-1) +2 \right| -1\]

Answer 18

Awesome! Thanks so much. I'm pretty sure I'll be able to the graph myself. You're the best! <3

Answer 19

You're welcome, anytime!

Answer 20

wait, I actually have one quick question, Doesn't the 'Show your work' column look a bit empty, are we supposed to add anything else there? @FortyTheRapper

Answer 21

Nah, that's all that is necessary

You could put y = in front of each one of those expressions, so they turn into valid equations

Answer 22

Awesome. alright. Thanks again!
