) Consider the following function: f₁ R → R given by f₁(x): Decide whether this function is injective, surjective, a bijection. fi is an injection: Not Answered fi is a surjection: Not Answered f₁ is a bijection: Not Answered = -3x4 - 5. ) Let the set A = {-1,0, 1} and consider the following function: f₂ : A → A given by f₂(x) = -(-x)³. You are required to state whether this function is injective, surjective, a bijection. f2 is an injection: Not Answered f2 is a surjection: Not Answered f2 is a bijection: Not Answered
