Thus, the largest possible value of \( y \) is \(\boxed20\).**Question:** A linguist studying phonetic transformations models a sound wave as \( f(x) = a \sin(bx + c) + d \). Given that the maximum amplitude is 3, the period is \( \pi \), and the wave passes through the origin, find the values of \( a, b, c, \) and \( d \). - Feedz API
