Question

Quiz.

f(x) = 4x - 2
g(x) = 2x² + 5 - 4

(g o f)(x) = ....??

​

Answer 1

Penjelasan dengan langkah-langkah:

f(x) = 4x - 2

g(x) = 2x² + 5 - 4

(g o f)(x)

g(f(x))

2(4x - 2)² + 5 - 4

= 2(16x² - 16x + 4) + 1

= 32x² - 32x + 8 + 1

= 32x² - 32x + 9

Answer 2

Jawaban:

asumsi 1: 32x²-32x+9

asumsi 2: 32x²-12x-6

Penjelasan dengan langkah-langkah:

= g(f(x))

= g(4x-2)

= 2(4x-2)²+5 - 4

= 2(16x²-16x+4)+1

= 32x²-32x+9

asumsi 2:

g(x)= 2x²+5x-4

= 32x²-32x+8+5(4x-2)-4

= 32x²-12x-6
