" How would I graph this? y=6, for x>2 y=3x, for 0 is less than or equal to x which is less than or equalto 2 y= -x, for x is less than or equal to 0" I assume you are asking how to enter it in a graphing calculator. If so, the commands on a TI-83 calculator would be: Y1 = (6)/(x>2) Y2 = (3x)/(x>0)/(x<2) "note that you will need the > or = symbol" Y3 = (-1/2x)/(x<0) "you will need the < or = symbol here" The necessary inequality symbols are available under math/test/ on the TI-83's I hope this helps!
