Given that f(x) = 2x+1 and g(x) = 3x2, what value(s) of x are excluded from the domain of (f/g)(x)?
I know how to set it up, but I don't understand the whole "exclusion" of the "domain"

Best ResponseYou've already chosen the best response.0Yeah like when the = sign has a / across it, right? Would I divide 2x by 3x and 1 by 2?

Best ResponseYou've already chosen the best response.0Would I have to do the same thing to the numbers on the top? like 2x+1=0

Best ResponseYou've already chosen the best response.3remember: when we divide two numbers, the numerator can be anything, but the denominator cannot be 0

Best ResponseYou've already chosen the best response.0Ok, and then I would divide them together? or would I do KCF?

Best ResponseYou've already chosen the best response.3no, you're done here, you found x = 2/3, that's your answer.
