No it is not one-to-one because any horizontal line will intersect more than one point. 4.1 (10.) Decide whether each function as defined or graphed is one-to-one. 4 20 y x = + ( ) ( ) f a f b = 4 20 4 20 a b + = + 4 4 a b = a b = Because a horizontal line will only pass through one point it is one-to-one .
