》Fungsi Komposisi

1. f(x) = 3x

f(7) = 3.7

f(7) = 21

2. 3/x = 1/2

x = 3 × 2 ÷ 1

x = 6 ÷ 1

x = 6

3. 2/4 = 5/b

b = 4 × 5 ÷ 2

b = 20 ÷ 2

b = 10

4. Volume =

= p.l.t

= 4 dm. 3 dm. 2 dm

= 24 dm³

= 24 liter

5. Bentuk Umum f(x) = ax + b

3a + b = 9

-3a + b = 9

b = 9 + 3a

3a + 9 + 3a = 9

6a = 0

  • a = 0

b = 9 + 3a

b = 9 + 3.0

b = 9 + 0

b = 9

Maka f(x) = ax + b

f(x) = 0x + 9
