Best ResponseYou've already chosen the best response.2g is a line y=x for all x\(\ge\)0 f is a line y=x for all x, besides x=0 h is just a line y=x

Best ResponseYou've already chosen the best response.2none of them are absolutely the same thing, but the closest ones I would say are f and h

Best ResponseYou've already chosen the best response.0@Vocaloid for the first one, I think zero is not allowed the domain.

Best ResponseYou've already chosen the best response.0^right, I didn't see that before, thank you

Best ResponseYou've already chosen the best response.0so I would say that none of them are the same

Best ResponseYou've already chosen the best response.2you have almost got the absolute value in g, Absolute value definition: D = sqrt (D^2)

Best ResponseYou've already chosen the best response.2None of them have the same domains!

Best ResponseYou've already chosen the best response.2but switching the order of ^2 and square root eliminates the left side of the absolute value function, making it y=x for all x>=0. (as I said before)

Best ResponseYou've already chosen the best response.2yes, none of them have the same exact domains

Best ResponseYou've already chosen the best response.1is the answer "none of these" as all are saying domain is not same.

Best ResponseYou've already chosen the best response.1@SolomonZelman are u saying that f(x)=g(x) and option i) is correct ?

Best ResponseYou've already chosen the best response.1i mean * are u saying that f(x)=h(x) and option i) is correct ?
