Determine whether the function f from { a, b, c, d} to { a, b, c, d} is injective (one - to - one), surjective (onto) and/or bijective (one - to - one correspondence) : f(a) = a, f(b) = a,f(c) = b, f(d) = c No points without explanations : 1.Is this function injective? If not, explain: 2. Is this function surjective? If not, explain: 3. Is this function bijective? If not, explain: 4.Is there an inverse for this function? Explain.
