Which two functions are inverses of each other?
f(x) = x, g(x) = –x
f(x) = 2x, g(x) =(1/2)x
f(x) = 4x, g(x) = (1/4)x
f(x) = –8x, g(x) = 8x

Best ResponseYou've already chosen the best response.0f(x) and g(x) are inverses iff f(g(x))=x and g(f(x))=x

Best ResponseYou've already chosen the best response.0so for example if f(x)= x and g(x)=x then f(g(x))=f(x)=x but this is not x so the first one is not a pair of inverse functions you try the others
