using a ti 89
posted by Cody on .
i am attempting to graph the piecewise function
y=(2/3)x6 if 9<=x<6
(1/3)x if 6<=x<0
(((x3)^2)/9) + (((y0)^2)/16)=1 if 0<=x<=6
on a ti 89 titanium. i believe you must use the when( feature, but i haven't a clue as to how. we are using transformations of piecewise functions and i wish to use this to check my graphs
