Question 49

Multiple Choice

Determine whether the functions f(x) f(x) and g(x) g(x) are inverse functions.
- f(x) =x10x+8f(x) =\frac{x-10}{x+8}


A) f1(x) =x+108+xf 1(x) =\frac{x+10}{8+x}

B) f1(x) =8x1x10f^{-1}(x) =\frac{-8 x-1}{x-10}

C) f1(x) =8x10x1f^{1}(x) =\frac{8 x-10}{x-1}

D) f1(x) =8x10x1f^{-1}(x) =\frac{-8 x-10}{x-1}
