tolong bantu dong 1. jika f(x) = x²-2x+1 maka f-1 (x) 2.jika f(x) = x²-4x+4 dengan x>2 maka f-1 (1) 3.jika f(x) = x²-4x-3 maka f-1 (x) 4. jika f(x) = 2x²+3x-1 m

[tex]1. \: f(x) = {x}^{2} - 2x + 1 \\ {f}^{ - 1} (x) = \sqrt{x} + 1 \\ 2. \: f(x) = {x}^{2} - 4x + 4 \\ {f}^{ - 1} (x) = \sqrt{x } + 2 \\ {f}^{ -1} (1) = \sqrt{1} + 2 = 3 \\ 3. \: {f}^{ } (x) = {x}^{2} - 4x - 3 \\ {f}^{ - 1} (x) = \sqrt{x + 7} + 2 \\ 4.f(x) = 2 {x}^{2} + 3x - 1 \\ {f}^{ - 1} (x) = [/tex]
