Answer 1

$\sf Answer$

$\sf c) f_{3}(x)$

$\sf Given$

$\sf \: f_{1}(x) = \frac{1}{x} \\ \sf f_{2}(x) = 1 - x \\ \sf f_{3}(x) = \frac{1}{1 - x} \\ \sf(f_{2} \times J \times f_{1})(x) = f_{3}(x) \\ \sf f_{2}( J \times f_{1})(x) ))= f_{3}(x) \\ \sf f_{2} \times J\binom{1}{x} = \frac{1}{1 - x} \\ \sf 1 - J\binom{1}{x} = \frac{1}{1 - x} \\ \sf J\binom{1}{x} = 1 - \frac{1}{1 - x} = \sf\frac{ - x}{1 - x} = \frac{x}{x - 1} \\ \sf now \: \: \: \: \: \: \: \: \: \: \: \: \: \: x ➝ \frac{1}{x} \\ \sf J(x) = \frac{1 \div x }{1 \div x - 1 = \frac{1}{1 - x} } = f_{3}(x)$
