Best ResponseYou've already chosen the best response.1\(\bf f(x)={\color{blue}{ y}}=0\qquad {\color{blue}{ f(x)}}=\cfrac{3x4}{5}\qquad thus \\ \quad \\ {\color{blue}{ 0}}=\cfrac{3x4}{5}\impliedby \textit{solve for "x"}\)

Best ResponseYou've already chosen the best response.0I know the answer it 4/3 its just I am having trouble understanding how. You guys are all saying different things and it's confusing. Like can someone just break it down barney style without being rude?

Best ResponseYou've already chosen the best response.1oh and i forgot to add what I said @freckles said f(x)=0 when the numerator=0

Best ResponseYou've already chosen the best response.1\[h(x)=\frac{f(x)}{g(x)}=0 \text{ when } f(x)=0 \text{ when } x \text{ is in the domain of } h \]

Best ResponseYou've already chosen the best response.1the only that gets to decide a fraction is 0 when the top is 0 on that function's domain of course

Best ResponseYou've already chosen the best response.1though you could have also decide to multiply both sides by 5 and that also works
