f(2x+1)=6x-5 tolong cari nilai f(x)

f(2x + 1) = 6x - 5
f(x) = a ?

x / 2x + 1 = 6x - 5 / a
a = (2x + 1)(6x - 5) / x
a = (12x^2 - 10x + 6x - 5) / x
a = (12x^2 - 4x - 5) / x
a = 12x - 4 - (5/x)

#semoga membantu...


Jadi,nilai f(x) = 12x - 4 - (5/x)

f(2x+1)= 6x-5

misal
2x+1= p
x= p-1/2

6(p-1/2)-5= f(p)
6p-6/2-5= f(p)

6p-6-10
_________ = f(p)
2

6p-16
______ = f(p)
2

6x-16
______ = f(x)
2



maap kalo salah
