Question 720966: how do you write piecewise functions?
f(x)={2x+1 , x≥1
{x/2-3 , x<1

You can put this solution on YOUR website!
f(x) = 

The graph of y=2x+1 is the red line.
It is drawn solid to the right of where x=1
The graph of y=x%2F2-3 is the green line
It is drawn solid to the left of where x=1.



We erase the dotted parts:



The red line includes the endpoint (1,3), so we place
a darkened circle at (1,3).  The green line does not
include the endpoint (1,-2.5) so we draw an open circle
there:
