b. B={( , ): (1,2), (3,2), (4,3), (5,2)}

c. =

d. =

e. + = 4

2. Tentukan daerah definisi dan daerah Nilai fungsi-fungsi berikut;

a. ( ) = − + 2 − 1 b. ( ) = √

c. ( ) = d. ( ) = |cos (x)|

Jawaban
1. a. Bukan fungsi b. Fungsi c. Fungsi d. Bukan fungsi e. Bukan fungsi

2. a. = ℝ , = (−∞, 0] b. = (−∞, −1) ∪ (1, +∞), = (−1,0] ∪ (1, +∞)

c. = ℝ − {3}, = ℝ − {7} d. = ℝ, = [0,1]
