## Gr. 11 Functions - Limiting domain and range on a graphing calculator [closed]

I'm trying to do a homework assignment on my graphing calculator app for my ipad (Quick graph+).

Looking at the images here: http://imgur.com/a/XRj4g

The first image at the top right is what I am trying to make on my graphing calculator. Basically I have to limit the domain when graphing. Halfway down in the red box I highlighted is the ears that we have to graph by limiting f(x)=-2abs(2x-5)+6 to a domain of 1<=x<=4

At the bottom right of the first image you can see how they insert it into the graphing calculator they use. They put f(x)=(-2abs(2x-5)+6)((x<=1)(x<=4)) however looking at the second image in the album my graphing calculator disallows that. I emailed the app creators and they said to use the "if" button. (image 3)

However when I used "if" it didn't turn out properly like I expected (image 4). I was wondering how I could go about properly graphing this function so it will limit the domain properly.

If there is any confusion in what I'm trying to do leave a comment and I'll try to explain my self further.

If this is not the correct website to post this question please redirect me to one.

Thanks alot, Matt
