دو تابع $f=\left\{ (2,5)\,,\,(1,4)\,,\,(5,3)\,,\,(6,2) \right\}$ و $g(x)=\frac{2x+5}{x-1}$ مفروضاند. برد تابع $(\frac{g}{f})(x)$ کدام است؟
1 )
$\left\{ \frac{7}{5},\frac{5}{2},\frac{17}{10} \right\}$
2 )
$\left\{ \frac{7}{5},\frac{5}{4},\frac{9}{10} \right\}$
3 )
$\left\{ \frac{9}{5},\frac{5}{2},\frac{8}{3} \right\}$
$\left\{ \frac{9}{5},\frac{5}{4},\frac{17}{10} \right\}$
