Can someone help me find the inequailty that belongs to this graph?!?

@freewilly922 Its asking me to write and Inequality for the graph...(:

OpenStudy (anonymous):

*an

OpenStudy (anonymous):

the easiest way to find this inequality is to graph the function. since it looks similar to f(x) = |x| you can just transpose the graph.

OpenStudy (anonymous):

Got it. Ok this is going to be an inequality of the form \[|x-p|+q\le y\] And we know this because the slope of the lines in the graph are 1 and -1. So in general we want to find (p,q) which is the vertex of the graph (the point place)

OpenStudy (anonymous):

So the point coordiantes is up one of five right?? where do I go from there

OpenStudy (anonymous):

(1,5)

OpenStudy (anonymous):

what do you have to do the graph of f(x) = |x| to get it to move +5 on the x axis and +1 on the y axis?

OpenStudy (anonymous):

Ok we what I meant by the slope part is that there isn't a pre factor by the absolute value bars that would squish or expand. up 1 would be q=1 and right 5 would be p=5 and then insert them into the equation.

OpenStudy (anonymous):

@Nameless has the right way of introducing the linear transformation though. I wish I explained it that way from the start....

OpenStudy (anonymous):

Ix-5I + 1 < y like that now do i solve that

OpenStudy (anonymous):

You don't. The question asked for the inequality for the graph. That's it:) I would suggest you understand the movements of the parent function y=|x-p|+q though...

OpenStudy (anonymous):

and it might be \[\le\] not <
