Basically:
- Look at the input voltage for a point
- Use the graph to find the corresponding output voltage
- Join the dots together (it will keep the same period and the same shape, either sine or the pointy triangle one, unless it is clipped)

So for the first one:
When Vin is 0V, Vout is 4V
When Vin is -0.2V, Vout is 0V
When Vin is 0.2V, Vout is 8V

2nd and 3rd are similar
For the 4th one, when Vin is between -0.3 and -0.2, Vout is 0. Similarly, when Vin is between 0.2 and 0.3, Vout is 8

Picture demonstrating how to draw the hard one (I assume you have the answers to all of them somewhere)

(yes I can't draw, pretend the lines kinda look like curvy where theyre supposed to be)
