1. Recall the definition of injection, surjection, and bijection given in Chapter 10. Establish which ones of the following functions are injections, surjections, and bijections. In case a function is not an injection, or not a surjection, or not a bijection, explain why. (a) f: {0, 1,2,3} → {♡,} such that ƒ(0) = f(1) = f(3) = ♡ and ƒ(2) = (b) g: {0, 1, 2, 3} → {0, 1, 4, 9} such that g(n) = n². (c) h: N→ N such that h(n) (d) k: Z→ N such that k(n) = |n|, the absolute value function. = n + 1.

1. Recall the definition of injection, surjection, and bijection given in Chapter 10. Establish which ones of the following functions are injections, surjections, and bijections. In case a function is not an injection, or not a surjection, or not a bijection, explain why. (a) \( f: \{0, 1, 2, 3\} \to \{\heartsuit, \spadesuit\} \) such that \( f(0) = f(1) = f(3) = \heartsuit \) and \( f(2) = \spadesuit \). (b) \( g: \{0, 1, 2, 3\} \to \{0, 1, 4, 9\} \) such that \( g(n) = n^2 \). (c) \( h: \mathbb{N} \to \mathbb{N} \) such that \( h(n) = n + 1 \). (d) \( k: \mathbb{Z} \to \mathbb{N} \) such that \( k(n) = |n| \), the absolute value function.
