Best ResponseYou've already chosen the best response.1we have f(x)= 6/(x4) x can't be 4 that'll make f(x) infinity so domain is all real numbers except 4 R{4}

Best ResponseYou've already chosen the best response.0technically not infinity, it'll be undefined

Best ResponseYou've already chosen the best response.0well how do you do the work to see f(x) = 6/(x4) please

Best ResponseYou've already chosen the best response.0domain is all the possible x values of a function which gives f(x) a value

Best ResponseYou've already chosen the best response.0you cannot divide a number by 0, because it will be undefined, thus f(x) won't be defined at that point

Best ResponseYou've already chosen the best response.0if x=4, f(x)=6/0 which is undefined

Best ResponseYou've already chosen the best response.0*f(4)=6/0 which is undefined
