ini bagaimana ka? yang per per gitu aku masi ga ngerti​

Jawaban:tentukan nilai fungsi-fungsi berikut ini berdasarkan domain yang diberikan: 1. f(x) = 5x - 2; A = {x | -5 ≤ x ≤ -1, x ∈ bilangan bulat} - Domain A = {-5, -4, -3, -2, -1}- f(-5) = 5(-5) - 2 = -25 - 2 = -27- f(-4) = 5(-4) - 2 = -20 - 2 = -22- f(-3) = 5(-3) - 2 = -15 - 2 = -17- f(-2) = 5(-2) - 2 = -10 - 2 = -12- f(-1) = 5(-1) - 2 = -5 - 2 = -7 2. f(x) = x² - 6x + 5; A = {x | -3 < x ≤ 2, x ∈ bilangan bulat} - Domain A = {-2, -1, 0, 1, 2}- f(-2) = (-2)² - 6(-2) + 5 = 4 + 12 + 5 = 21- f(-1) = (-1)² - 6(-1) + 5 = 1 + 6 + 5 = 12- f(0) = (0)² - 6(0) + 5 = 0 - 0 + 5 = 5- f(1) = (1)² - 6(1) + 5 = 1 - 6 + 5 = 0- f(2) = (2)² - 6(2) + 5 = 4 - 12 + 5 = -3 3. f(x) = 2x² + 2x + 1; A = {x | 2 ≤ x < 6, x ∈ bilangan bulat} - Domain A = {2, 3, 4, 5}- f(2) = 2(2)² + 2(2) + 1 = 8 + 4 + 1 = 13- f(3) = 2(3)² + 2(3) + 1 = 18 + 6 + 1 = 25- f(4) = 2(4)² + 2(4) + 1 = 32 + 8 + 1 = 41- f(5) = 2(5)² + 2(5) + 1 = 50 + 10 + 1 = 61 4. g(x) = (5x + 1) / 2; A = {x | -2 ≤ x ≤ 2, x ∈ bilangan bulat} - Domain A = {-2, -1, 0, 1, 2}- g(-2) = (5(-2) + 1) / 2 = (-10 + 1) / 2 = -9/2 = -4.5- g(-1) = (5(-1) + 1) / 2 = (-5 + 1) / 2 = -4/2 = -2- g(0) = (5(0) + 1) / 2 = (0 + 1) / 2 = 1/2 = 0.5- g(1) = (5(1) + 1) / 2 = (5 + 1) / 2 = 6/2 = 3- g(2) = (5(2) + 1) / 2 = (10 + 1) / 2 = 11/2 = 5.5 5. g(x) = (6x - 1) / 3; A = {x | -4 < x < 2, x ∈ bilangan bulat} - Domain A = {-3, -2, -1, 0, 1}- g(-3) = (6(-3) - 1) / 3 = (-18 - 1) / 3 = -19/3 ≈ -6.33- g(-2) = (6(-2) - 1) / 3 = (-12 - 1) / 3 = -13/3 ≈ -4.33- g(-1) = (6(-1) - 1) / 3 = (-6 - 1) / 3 = -7/3 ≈ -2.33- g(0) = (6(0) - 1) / 3 = (0 - 1) / 3 = -1/3 ≈ -0.33- g(1) = (6(1) - 1) / 3 = (6 - 1) / 3 = 5/3 ≈ 1.67maaf cuman bisa bantu segitu kolom jawabnya tidak muat
