Solution: দেয়া আছে, f(x) = 5 - 2x => f(3x) = 5 - (2 3k) f(3k) = 5 - 6k আবার, f(x) = 5 - 2x => f(k + 1) = 5 - 2 (k + 1) => f(k + 1) = 5 - 2k - 2 f(k + 1) = 3 - 2k প্রশ্নমতে, 5 - 6x = 3 - 2k => 6k - 2k = 5 - 3 => 4k = 2 k = 1/2 অতএব, f(k) = 5 - 2k => f(k) = 5 - => f(k) = 5 - 1 f(k) = 4Related questions
