  1. Value of f(2) for a quadratic ●●●○○ 50 ptsLet aa and bb be real numbers. The quadratic function f(x)=x2+ax+bf(x)=x^{2}+ax+b satisfies f(f(0))=f(f(1))=0f(f(0))=f(f(1))=0 and f(0)≠f(1)f(0)\neq f(1). Find f(2)f(2).
  2. Largest edge of a box ●●●○○ 50 ptsAn m×n×pm\times n\times p rectangular box has half the volume of an (m+2)×(n+2)×(p+2)(m + 2)\times(n + 2)\times(p + 2) rectangular box, where m,n,m, n, and pp are positive integers with m≤n≤pm\le n\le p. Find the largest possible value of pp.
  3. Common ratio from a sum relation ●●●○○ 50 ptsLet SnS_n be the sum of the first nn terms of a geometric sequence {an}\{a_n\} with nonzero first term and common ratio qq. Given that S4=5S2S_4 = 5S_2, find all possible values of qq, listed in increasing order.
