Which statement about composing two functions f and g is correct?
AComposition works for any two functions
BThe two orders can give different results
CComposition always yields an inverse
DThe two orders always give equal results
Answer & Solution
Correct answer: B. The two orders can give different results
Composition is not commutative; for f(x) = x^2 and g(x) = x + 1 the two orders differ.
