![**Problem 2:**
Consider the function \( f : (a, b) \to \mathbb{R} \). Assume there exist constants \( M > 0 \) and \( \alpha > 1 \) such that:
\[ |f(x) - f(y)| \leq M |x - y|^\alpha \]
for all \( x, y \in (a, b) \). Your task is to prove or disprove that \( f \) is a constant function.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fabba7d05-e030-4d49-ac3b-b588659cd1ab%2Ff4e4159f-d030-42cc-8280-977b4a779c02%2F6774i4d_processed.png&w=3840&q=75)
