F(x) = 3x - 6
g(x) = x - 2
This means the value of the ratio f(x)/g(x) will be equal to 3.
Domain of the fraction is Set of All real numbers except 2. At 2 the given fraction will be undefined as the denominator in the very first fraction will be zero. Another reason 2 is not a part of the domain is that it will make x-2 equal to zero and we cannot cancel out 0 with 0 from numerator and denominator.
In interval notation, the domain will be: (-∞,2)∪(-2 ,∞)
g(x) = x - 2
