diketahui Dua Buah fungsi f(x)=2-a/2x Dan g(x)=2-(a-3) jika f(x)=g(x),tentukan. A. nilai a.

a.). f(x) = g(x)
misal, x=1, maka
2-a/2(1) = 2(a-3)1
2-a/2= 2(a-3)
-a/2 = -a+3
-a = ( -a+3) 2
-a = -2a+6
-a+2a= 6
a=6

b.) f(x) = 2-a/2x
= 2-6/2x
= 2-3x
g(x) = 2-(a-3)x
= 2-(6-3)x
= 2-3x
c.) f(x)+g(x)= (2-3x)+(2-3x)
= 4-6x
d.) f(1)=2-3(1)
= -1
f(2)= 2-3(2) = -4
g(1)= 2-3(1)=-1
g(4)=2-3(4)=-10
