Answer:
B
Step-by-step explanation:
The range is the set of y-values for which the function is defined.
** Attached is the graph of the function
By looking at the graph, we can clearly see that there aren't any y-values that is not permitted in the graph. The function is defined for all y-values. Hence the range is set of all real numbers, or, the range is (-∞, +∞)
Answer choice B is right.
