Question

Diketahui f(x) = x - 2 gan g(x) = 3x - 1 tentukanlah. a,(f°g)(x) . b,(g°f)(x) dan c,(g°f)(-2)​

Answer 1

Verified answer

Diketahui:

f(x) = x-2

g(x) = 3x-1

Ditanyakan:

a. (fog)(x)

b. (gof)(x)

c. (gof)(-2)

Jawab:

a. (fog)(x)

= f(g(x))

= (g(x)) - 2

= 3x-1-2

= 3x-3

b. (gof)(x)

= (g(f(x))

= 3(f(x))-1

= 3(x-2)-1

= 3x-6-1

= 3x-7

c. (gof)(-2)

= 3(-2)-7

= -6-7

= -13
