Question

I'm currently working on this problem and I suck at linear functions, but I'm trying. Anyway here are the questions: https://www.dropbox.com/s/5040ghii3aq3wgy/Screen%20Shot%202015-07-08%20at%2012.12.07%20AM.png?dl=0

And here is my work (sorry for my handwriting) https://www.dropbox.com/sc/twrnm6rewhatdb1/AADu0k3vvr_GpeadZYmUQr1na

I'm mostly concerned about the graph. Should I make that kind of graph (the one on my paper) or should I make one of those with X and Y axis?

Answer 1

Part A looks good!

Answer 2

For Part B, shouldn't the domain include 0 also ?

Answer 3

domain should be 0 and all positive integers right ?

Answer 4

Because of the initial cost of the bracelet without any of the charms?

Answer 5

Exactly! what if they didn't buy any charms at all ? your function must give answer when x=0 also

Answer 6

Alright then :)
How about my graph? To me it looks pretty good xD but should I make one of those grid charts (I don't know what exactly they're called) with X and Y axis

Answer 7

What you had over there is a table, it is not graph.

Answer 8

Oh

Answer 9

The graph should look something like below

Answer 10

How do you make a graph on the computer?

Answer 11

Answer 12

That's awesome! Thank you! Anyway while you were doing your way which is superior to mine, i drew one (I'm a kinesthetic learner so I have to write everything down)
Mine looks good right? I labeled the axis correctly as well right?
