Tolong siapapun bantu,tolong ya ini saya butuh banget
Jawaban:
a. (f o g)(x)= 2x+7
b. (g o f)(x)= 2x+2
c. (f o f)(x)= 4x-9
d. (g o g)(x)= x+10
Penjelasan dengan langkah-langkah:
f(x)= 2x-3
g(x)= x+5
a.
(f o g)(x)
= f(g(x))
= f(x+5)
= 2(x+5)-3
= 2x+10-3
= 2x+7
b.
(g o f)(x)
= g(f(x))
= g(2x-3)
= (2x-3)+5
= 2x+2
c.
(f o f)(x)
= f(f(x))
= f(2x-3)
= 2(2x-3)-3
= 4x-6-3
= 4x-9
d.
(g o g)(x)
= g(g(x))
= g(x+5)
= (x+5)+5
= x+10
