Question

Select the graph of y = |x - 1| - 1
(graph will be attached below)

Answer 1

I'd suggest that your best bet in answering this question would be to consider how you"d graph this equation yourself: y = |x - 1| - 1

The graph of y=}x} alone is v-shaped:

Answer 2

How does the graph change if you go from y=|x| to y=|x-1|?

How does the graph change if you from y=|x-1| to y=(x-1| - 1 ?

Answer 3

If you do this correctly, it should be a snap for you to choose the correct answer.

Answer 4

i don't exactly understand ): @mathmale

Answer 5

The third one I think... Try graphing the equation on a graphing website and compare the graphs. I went and found it for you im pretty sure its the fourth one :)

Answer 6

See how it goes through zero? Like the third one

Answer 7

yeah yeah yeah you're a life saver

Answer 8

lol

Answer 9

@chariety101 : There are several ways in which to approach this problem. the one I've suggested is, I believe, the best: you need to know how to graph

y=|x|,
y=|x-1|, and
y=|x-1|-1

Yourself.

Answer 10

Now, if you go from the equation y=|x| to y=|x-1|, the result is that your graph (all of it) will shift one unit to the right, which is in the positive x-direction:

Answer 11

Answer 12

Now, how does the graph change if we go from y=|x-1| to y=|x-1|-1?
Answer: the graph will look exactly the same, EXCEPT that we move everything downward
1 unit from (1,0).

Please graph this yourself. copy my diagram and edit it.
