and I have to sketch it I'm completely lost

3. anonymous

hmm...

4. anonymous

I'm sure you really are a life saver

5. anonymous

well, the way to sketch a "piece-wise" defined function is to attack each "piece" separately

6. anonymous

this is difficult to explain in words...

7. anonymous

ok

8. anonymous

do I always use 0,1,and 2 to enter into the equation?

9. anonymous

to figure out what goes where?

10. anonymous

first lets get the function written in notation so we can see what we are dealing with...one second

11. anonymous

There are four parts to this question. a) find the domain, b) locate any intercepts, c) graph each function and d) based on the graph find the range. I don't understand where to start on any of it.

12. anonymous

I had the flu and missed one class and I don't understand

13. anonymous

this is what I think the function is...$f(x)=x+3$, if $-2\leq x <1$, 5 if $x=1$, $-x+2$ if $x>1$

14. anonymous

no worries, I just wanted to make sure I understood the function before starting an explanation

15. anonymous

yes thank you

16. anonymous

my suggestion is this, first mark your intervals on the x-axis with the appropriate (,),[, or ] notation

17. anonymous

then sketch the graph of the function with the rule that pertains to the appropriate interval

18. anonymous

this is a 5 second explanation with on a dry erase board...

19. anonymous

i suggest looking on youtube for a video demostration

20. anonymous

demonstration

21. anonymous

now what? I don't know anything about u tube or how to get a math video, I lucked out with you guys

22. anonymous

hello?
