pakai caraaa yaa terimakasih:)

f(x) = 3x - 5

x = {-1, 0, 1, 2, 3}

a. Daerah Hasil
x = -1 → f(-1) = 3(-1) - 5 = - 3 - 5 = - 8
x = 0 → f(0) = 3(0) - 5 = 0 - 5 = - 5
x = 1 → f(1) = 3(1) - 5 = 3 - 5 = - 2
x = 2 → f(2) = 3(2) - 5 = 6 - 5 = 1
x = 3 → f(3) = 3(3) - 5 = 9 - 5 = 4

f(x) = {-8, -5, -2, 1, 4} 

b. Nilai dari f(¹/₃)

f(¹/₃) = 3(¹/₃) - 5 = 1 - 5 = - 4

c. f(a) = 19 → x = a 
   
    3a - 5 = 19
    3a = 19 + 5
    3a = 24
      a = 24 ÷ 3
      a = 8
