1. The problem statement, all variables and given/known data Find a formula for one function that satisfies these given conditions: 1.) f is continuous on [0,1]. 2.) f(0) = f(1) = 0 (exactly). 3.) f(x) is greater than or equal to 0 for [0,1] 4.) The area under the graph of f from 0 to 1 is equal to 1 (exactly). Calculate the arc length. Try to find the smallest possible arc length. 2. Relevant equations Arc Length formula 3. The attempt at a solution I don't know! I'm completely lost. So far I found the function f(x) = -6x^2+6x gives me an arc length of ~3.249 and satisfies all four conditions. But I'm pretty sure there must be a smaller arc length. Please help me find the smallest possible arc length. Thank you!
