Let f(x)=3x-6 and g(x)=x-2. find the g/f and state its domain.

Answers

$f(x)=3x-6;\ g(x)=x-2\n\n(g(x))/(f(x))=(x-2)/(3x-6)=(x-2)/(3(x-2))=(1)/(3)\n\nDomain:x\in\mathbb{R}\ \backslash\ \{2\}$

$f(x)=3x-6\n \n g(x)=x-2\n \n (g(x))/(f(x))=(x-2)/(3x-6)=(x-2)/(3(x-2))=(1)/(3)\n \n D\left((g(x))/(f(x))\right)= R$
