Answer:
all real numbers
Step-by-step explanation:
"Range" usually refers to the vertical extent of the graph of a function (possible y-values). "What x is less than or greater than" is usually referred to as the "domain."
Either way, both the domain and range of the function written here are "all real numbers." Both x and y can take on any value you like.
-∞ < x < ∞
