SOLUTION: Hello,
Can someone please help me find the domain of this rational function?:
f(x)= x((6x+176)/x-4) [or f(x)= (6x^2 + 176 x) / (x-4) in "simplified" form].

All I understand about a domain is that it is all the values of 'x' for which f(x) is a real number.
I don't really understand domains when doing rational functions, so help would be greatly appreciated.
Thank-you! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! 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
