Graph y=/x/-2
I assume you mean this right? \[\Large y = |x| - 2\]
I would graph it using something like desmos https://www.desmos.com/calculator
type in `y = abs(x) - 2` the "abs" means "absolute value function"
so the answer is C???
yeah this one http://assets.openstudy.com/updates/attachments/564949fde4b0542a6dd50ce8-cookiemonster18-1447643713154-untitled3.png
thank you @jim_thompson5910
you're welcome
can you help with 3 more? @jim_thompson5910
sure post each as a new question and tag me in it post one at a time
1.Graph y=-/x-4/
2.write an equation for the transformation of y=/x/ A.y=/x/+2 B.y=/x/-2 C.y=/x-2/ D.y=/-2x/
First off, please post ONE at a time.
I would graph just like in the previous problem. Any ideas what to type into desmos?
oh sorry thought you meant post all of them 1 by 1, not post 1 answer 1 then post the other. my apology.
well it makes it easier to post one at a time so we don't get confused on which one we're working on currently
ok okay and no I have no clue on what to type for the "desmos".
btw, type | instead of / to mean absolute value so instead of `y=-/x-4/` type this `y = -|x-4|`
to graph `y = -|x-4|` you would type `y = -abs(x-4)` into desmos
whatever is in the parenthesis of the "abs" is what goes in the absolute value bars
umm...I cant find any place that would graph that so ima guess that it's B
desmos doesn't work?
D :/ ?
can you show me a screenshot of what graph you get when you type into desmos
@jim_thompson5910
why are you that zoomed out? you should zoom in until you can see the vertex a bit better
sorry meant to send this one
ok much better
so the answer this one is D?
so now we're one #2 @jim_thompson5910
ok post that one
2.write an equation for the transformation of y=/x/ A.y=/x/+2 B.y=/x/-2 C.y=/x-2/ D.y=/-2x/ @jim_thompson5910
I'm lost. Was there a graph given here? or no?
no
do they give instructions like "shift up 2 units" or something?
it just want us to write an equation for the transformation of y=/x/
can you post a screenshot of the full problem?
sure @jim_thompson5910
ok thanks
you just tack on a `-2` to shift all of the original parent function 2 units down
so the answer is B @jim_thompson5910 ??? I don't quit understand what you mean
yes `y = |x| - 2`
now we can work on #3 and we'll be done :)) thank you @jim_thompson5910 for helping me this far
