1. **Problem Statement:** Determine the range of the function given the points at $x=1$ with $y$-values 2, 3, 4, and 5. 2. **Understanding the Range:** The range of a function is the set of all possible output values ($y$-values). 3. **Given Data:** The function has points at $x=1$ with $y=2, 3, 4, 5$. 4. **Range Determination:** Since the function only takes these $y$-values at $x=1$, the range is the set of these values. 5. **Final Answer:** The range is $$\{2, 3, 4, 5\}$$.
