Answer 2

Penjelasan dengan langkah-langkah:

3a] f(x) = 7x + 9

g(x) = 3 . (2 - 3x)

g(x) = 6 - 9x

(f - g) (x)

= 7x + 9 - (6 - 9x)

= 7x + 9 - 6 + 9x

= 16x + 3

(f + g) (x)

= 7x + 9 + 6 - 9x

= -2x + 15

(f : g) (x) = (7x + 9)/(6 - 9x)

(f : g) (1)

= (7 . 1 + 9)/(6 - 9 . 1)

= 16/-3

= -16/3

= -5 1/3

b] f(x) = 4x + 3

f(x²) = 4x² + 3

(f(x))² = (4x + 3)² = 16x² + 24x + 9

2 f(x) = 2 . (4x + 3) = 8x + 6

f(x²) + (f(x))² - 2 f(x)

= 4x² + 3 + 16x² + 24x + 9 - (8x + 6)

= 20x² + 24x - 8x + 12 - 6

= 20x² + 16x + 6
