Answer 1

Verified answer

Penyelesaian

f(x)=x²+5x-6

g(x)=x-1

.

(f o g)(x)=f(g(x))

x²+5x-6

=(x-1)²+5(x-1)-6

=x²-2x+1+5x-5-6

=x²+3x-10(a.)

Answer 2

KOMposisi FungsI

fungsi f(x) = x² + 5x - 6 dan g(x)=x-1.
(fog)(x)=

=  f {g(x)}

=  f(x - 1)
= (x - 1)² + 5(x - 1) -  6
= x² - 2x + 1 + 5x -  5 - 6
= x² +  3x  - 10
