Question

What is the range of this piecewise function?

Answer 1

I'm really trying to decide between option b and d here, but I have no idea what the different parentheses mean.

Answer 2

The shape is a bit unclear at boundaries

Answer 3

It doesn't clear for me that whether the left piece goes at infinity?

Answer 4

The picture tells us that the domain of the function is placed between (-2, 4] and the function range of the function is (+infinity, 2] + (0, -4]. note that the point zero is deleted

Answer 5

So b is true

Answer 6

Understood?

Answer 7

Yes, I understand! Thank you so much.
