kakak yang jago matematika bantu jawab ya

a) jadikan f(invers)
= f(x) = x-3
y = x-3
y+3= x
f(invers) (x) = x+3
f(invers) o g = f(invers) (g(x))
= f(invers) (2x+4)
= (2x+4)+3
= 2x+7
b) jadikan g(invers)
g(x) = 2x+4
y = 2x+4
-2x = -y+4
x = -y+4/2
g(invers) (x) = -x+4/2
f o g(invers) = f (g(invers)(x))
= f ( -x+4/2)
= (-x+4/2)-3
= -x-2/2
c) f(invers) o g(invers)
= (-x+4/2)+3
= -x+10/2
d) (f o g)(invers)
= (2x+4)-3
= 2x+1
( invers) (x)
(fog) (invers) (x)
= 2x+1
