Answer 1

Jawaban:

2. a) 8x - 34

b) 8x - 19

3. a) 6x² + 8x + 1

Penjelasan dengan langkah-langkah:

2. a. fog(x) = f x g(x)

= f (2x - 7) - 6

= 4 (2x - 7) - 6

= 8x - 28 - 6

= 8x - 34

b. gof(x) = g x f(x)

= g (4x - 6) - 7

= 2 (4x - 6) - 7

= 8x - 12 - 7

= 8x - 19

3. a. fog(x) = f x g(x)

= f (2x)

= 3(2x)² + 4(2x) + 1

= 6x² + 8x + 1
