Question 21

D Question 21 Which statements are true for inverse functions? Choose ALL that apply. The domain of f (a ) is the range of f (a) and the range of f (a) is the domain of f- (a). O ( f of 1 ) ( 20 ) = (f- 1 0 f ) (20) = z The graphs of f (a) and f-1 (a) are symmetric about the line y = X. O Only f (a) , not f 1 (a) , is one-to-one
