Question

Dik. fungsi f(x) = x + 4, dan g(x) = x² - 3x +7. fungsi komposisi (g°f) (x) = ....

Answer 1

Makasih semoga membantu

Answer 2

Diketahui : f(x) = x+4
g(x) = x² - 3x + 7

Ditanya : ( g ○ f ) (x) = ...?

Jawab : ( g ○ f) (x)
= g(f(x))
=x²-3x+7(x+4)
=(x+4)²-3(x+4)+7
=x²+8x+16-3x+12+7
=x²+5x+35
