The correct answer is:
domain: all real numbers; range: all real numbers; Yes, it is a function.
Find the domain and range of the relation and determine whether it is a function.
Question 4 graphA graph with horizontal axis x range from left to right labeled is negative 4 to 4; vertical axis y labeled from top to bottom is range from 4 to negative 4.
The graph shows an upward going curve starting from around left parenthesis 1 comma 0 right parenthesis. The curve goes toward the left sharply upward close along the right side of vertical asymptote x equals negative 2.
