Question

ka caranya gimana ya :')​

Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

f(x) = 2x

g(x) = -x

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

f(x) . g(x) = -2x²

b. (f.g)(2) = -2 (2²)

(f.g)(2) = -2 (4)

(f.g)(2) = -8

c. (f . f)(x) = (2x) (2x)

(f . f)(x) = 4x²

(f . f)(4) = 4 (4²)

(f . f)(4) = 4 (16)

(f . f)(4) = 64
