jawab sekarang please!!!

f(x)= 3x + 4

3x + 4 = y
3x = y - 4
x = (y-4) /3
f⁻¹ (x)  = (x - 4) / 3
f⁻¹ (x)= g(x)


g(x) = (x - 4)/ 3
(x - 4)/3 = y
x - 4 = 3y
x = 3y + 4
g⁻¹ (x) = 3x + 4
g⁻¹ (x) = f (x) 

Jawabannya::
3x+4y=y
3x=y-4
x=(y-4)/3
f^-1(x)=(x-4)/3
f^-1(x)=g(x)

g(x)=(x-4)/3
(x-4)/3=y
x-4=3y
x=3y+4
g^-1(x)=3x+4
g^-1(x)=f(x)
