False: does a circle represents a one-to-one function, true b. 126 c. 9 d. 55 e. 72: using the function values for f and g in the table below, what is (g f )( 1)? x f (x) g(x) 0 c. 4 d. 7 e. 10: let f and g be functions such that f (x) = x + 1 and g(x) = x2 1, respectively. Is f (g(x)) = x: true b. False: let f be a function where f (x) = 1 x 1: (f f )(x) , (f f )(x) = 1 x x x + 2 x: (f f )(x) =
