Question 860599
f(x)= x((6x+176)/x-4)
f(x) = 2x(3x+88) / (x-4)
when looking at the domain of a rational function, we must exclude any value of x that makes the denominator 0 since division by 0 is not defined
now the denominator (x-4) is 0 if x = 4
therefore the domain for x is all real values of x except 4
