Best ResponseYou've already chosen the best response.0check which function gives f(x). example x=0 ,f(x)=1 so which function gives 1? then check the next

Best ResponseYou've already chosen the best response.0lets take a look at D. If you use f(x) = x1 and plug values in... start with 0. the table tells you that when x=0, f(x) = 1 using equation D, f(0) = 01 = 1. They don't match up so it can't be D!

Best ResponseYou've already chosen the best response.0no your answer is wrong. the function D is f(x)= x1 so if x=0, f(x) =01=1 which doesn't correspond with the given example

Best ResponseYou've already chosen the best response.0so when i do A it comes out x=1/f1 b x=1/f c x=^x2/f i believe A comes to the best choice.

Best ResponseYou've already chosen the best response.0sorry, I'm not following your work. When did you divide by f?

Best ResponseYou've already chosen the best response.0But you are correct, A is the right answer. Just to recap, B is a constant function. f(x) = 1 is saying that no matter what x is, the function = 1. We know thats not true by looking at every entry but the first in the table. C is saying square your x (unless its 2*x.. either way its wrong) plug in x = 2, x^2 = 4, not 3 so C doesn't work either
