Question

What is the answer to:

A student was asked to find the domain and range of the following graph. However, a mistake was made.

Part A (1 point): Identify the mistake made (be specific as possible)
Part B (1 point): Correct the mistake by showing your work.

Answer 1

the problem is the domain isn't closed because the there is a circle at the end instead of a period. I think it should be from 0<x infinite. and range should be infinite<y<4
hopefully that's right, someone correct me if I'm wrong
