100 Hikes / Travel Guide: Oregon Coast & Coast Range

Matematika f(x) = 2x dan g(x). tentukan fg(2)...​

f(x) = 2x dan g(x). tentukan fg(2)...​

Jawaban:

fog(x)=2x²+4

gof(x)= 4x²+4

Penjelasan dengan langkah-langkah:

Dik

f(x) = 2x

g(x)=x²+2

a. fog (x) = f(g(x))

= f(x²+2)

= 2x

= 2(x²+2)

= 2x²+4

b. gof (x)= g(f(x))

= g(2x)

= x²+2

= (2x)²+2

= 4ײ+4
