• which statement describes function composition with respect to the commutative property? given f(x) = x² – 4 and g(x) = x – 3, (f ∘ g)(2) = –3 and (g ∘ f)(2) = –3, so function composition is commutative. given f(x) = 2x – 5 and g(x) = 0.5x – 2.5, (f ∘ g)(x) = x and (g ∘ f)(x) = x, so function composition is commutative. given f(x) = x² and g(x) = startroot x endroot, (f ∘ g)(0) = 0 and (g ∘ f)(0) = 0, so function composition is not commutative. given f(x) = 4x and g(x) = x², (f ∘ g)(x) = 4x² and (g ∘ f)(x) = 16x², so function composition is not commutative.
