1. The problem asks: "There's only one range what is it?" This is ambiguous without context, but typically in math, "range" refers to the set of possible output values of a function. 2. To find the range of a function, we analyze the function's behavior and determine all possible output values. 3. For example, if the function is $y = x^2$, the range is all real numbers $y \geq 0$ because squaring any real number cannot produce a negative result. 4. Without a specific function or context, the "only one range" could mean the function's output is a single value, i.e., the range is a single number. 5. For instance, if $y = 5$, then the range is just $\{5\}$. 6. Please provide the function or more context to determine the exact range.
