## anonymous 5 years ago How do i graph piecewise functions?

1. anonymous

draw different functions in different intercals on the same graph

2. anonymous

intervals*

3. anonymous

for eg y=|x| can be broken into y=-x, x<0 y=x , x>0 so u can draw y=-x, a line in the region x<0 and y=x in region x>0

You can look at my video here about how to graph a piecewise function :D http://www.youtube.com/watch?v=9aXoOhNK_-s&feature=fvsr

equation: $3x squared +15x+17=0$ answer: $X= -15x \pm \sqrt{21} \over 6$ How was this solvedd ?
