Diketahui sebuah fungsi f(x) = 4-3x. Tentukanlah:
a. f(5) =
b. f(-2) =
c. f(4) – f(-10) =

Jawab:

$a. -11\b. 10\c. -42$

Penjelasan dengan langkah-langkah:

$a. f(5) \= 4 - 3(5)\= 4 - 15\= -11\\b. f(-2)\= 4 - 3(-2)\= 10\\c. f(4) - f(-10)\= 4 - 3(4) - [4 - 3(-10)]\= -8 -34\= -42$

Jawab:

A. f(5) = -11

B. f(-2) = 10

C. f(4) – f(-10) = 18

Penjelasan dengan langkah-langkah:

A. f(5) = 4 – (3 x 5) = 4 – 15 = -11

B. f(-2) = 4 – (3 x (-2)) = 4 + 6 = 10

C. f(4) = 4 – (3 x 4) = 4 – 12 = -8

f(-10) = 4 – (3 x (-10)) = 4 + 30 = -26

f(4) – f(-10) = -8 – (-26) = -8 + 26 = 18

Semoga bermanfaat ^_^

Selamat belajar!!
