Question

Diketahui suatu fungsi f dengan daerah asal A = {6, 8, 10, 12} dengan rumus fungsi f(x) = 3x - 4.

a. Tentukan f(6), f(8), f(10), f(12).!
b. Nyatakan fungsi tersebut

Answer 1

F(6) = 3(6)-4
14
f(8) = 3(8)-4
20
f(10) = 3(10)-4
26
f(12) = 3(12)-4
32

Answer 2

A). f(6) = 3x - 4 = (3 x 6) - 4 = 14
f(8) = (3x8) - 4 = 24 - 4 = 20
f(10) = (3x10) - 4 = 30 - 4 = 26
f(12) = (3x12) - 4 = 36 - 4 = 32
