Do you know how a hybrid function works? If not, this is where you need to start. First look at the intervals for each function, and graph that function over those given x-values. Then, if the graphs do not connect at the endpoints of the intervals, then you need to use your "greater than or equal to/less than or equal to" signs on the interval notation to find out whether to use an open end dot or a closed end dot. (In both of these questions they do join at all points, so this part doesn't matter)

In general, just substitute the endpoints into the equation to find the junctions of the hybrid function, and then graph between them. Hope this helps!

This is just 2/3 (depending on how many functions they give you) different graphs joined together. Good way to start sketching this is what yertle is talking about, finding the end points using the domain
For example: f(0)= 2/3(0)+3 = 3 , f(0)= 0+3=3, f(1)=1+3=4, f(1)= -2(1)+6=4 [q2]
After that, draw in little dots to see if the function joins together but typically it does and graph the separate functions together as one. Ultimately you could always draw the whole function then rub out what you don't need and, on the graph page of the cas calc. 1) press the 3 box button next to the book symbol , 2) choose which piece wise graph option you want, in this case the 6 box one (you can use the 4 box option in q4-6), 3) type in your function with the restricted domain after the comma symbol.

Good luck
