( a) 9 O b) 4 O c) 18 O d) 3 Question 3 (1 point) The composite function (f . g)(x) is defined only when. ( a) the domain of f and the range of g overlap ( b) the domains of f and g are equal c) the domains of f and g overlap O d) the range of f and the domain of g overlap Question 4 (1 point) The composite function (f . f-1)(x) is equal to. ( a) f(x) b ) x O c) F( x ) f - 1 ( x ) O d ) f- 1 ( x )
