I feel like this might be a dumb question, but I'm trying to figure out what this question means by the scale of the x-axis.. previous questions were asking for ticks and that leads me to believe the scale would be 5 ticks. However I also believe the scale could be 1 since each vale of x=1. Additionally I'm confused about question 10 which asks if there are any discontinuities. Any help would be greatly appreciated!

9. Zoom in twice more. Display the graph below and state the scale of the x-axis. -1 'f 10. Are there any breaks (discontinuities) in the graph of f (x)
