Question

Poinnya lumayan tuh
Tolong jawab semuanya pake cara yaa

Jika diketahui fungsi f(x) = 3x+5, g(x) = 2x, dan h(x) = x^2+2, tentukan :
a. (f o g)
b. (g o h)
c. (f o g) o h
d. f o (g o h)

Answer 1

Verified answer

F(x) = 3x + 5
g(x) = 2x
h(x) = x² + 2

a.
(f o g)(x)
= 3(2x) + 5
= 6x + 5

b.
(g o h)(x)
= 2(x² + 2)
= 2x² + 4

c.
((f o g) o h)(x)
= 6(x² + 2) + 5
= 6x² + 12 + 5
= 6x² + 17

d. f o (g o h)
= 3(2x² + 4) + 5
= 6x² + 12 + 5
= 6x² + 17
