bismillah, tolong dibantu ya akang akang sekalian....

f(x) = 2x + 5
g(x) = (x - 1)/(x + 5) x =/= -5
(f○g)(x) = f○(g(x))
= f○((x - 1)/(x + 5))
= 2((x - 1)/(x + 5)) + 5
= [(2x - 2)/(x + 5)] + [5(x + 5)/(x + 5)]
= [(2x - 2)/(x + 5)] + [(5x + 25)/(x + 5)]
= (7x + 23)/(x + 5) x =/= - 5

itu kemungkinan soalnya ada yang kurang tepat soalnya xbukan samadengan -5,jadi jawabnya kalo gitu f(g(x))=2(x-1)/(x+5)+5
=2x-2+5x+25/x+5= 7x+23/x+5 dimana x bukan samadengan 5
