Question

Use interval notation to indicate where f(x) is continuous. If it is continuous on more than one interval, use U for union.

Answer 1

[-2,0)U(0,1)U(1,4] actually.

Answer 2

that's what I thought, but apparently incorrect.

Answer 3

Really? The only other way I can think of it would be: [-2,-1)U(-1,0)U(0,1)U(1,4]

Answer 4

Because the circles are "technically" removable discontinuities.

Answer 5

ahh, there it is. Cheers :]

Answer 6
