Suatu fungsi di rumuskan f(×)=a×+b.jika f(-2)=14 dan f(3)=-1 maka nilai a dan b berturut turut adalah Plies jawabb,besokk kumpul

f(-2) = 14
14 = a.-2 + b
-2a + b = 14
b = 2a + 14
f(3) = -1
a.3 + b = -1
3a + 2a + 14 = -1
5a + 14 = -1
5a = -1 - 14
5a = -15
a = -15/5
a = -3
b = 2a + 14
b = 2(-3) + 14
b = -6 + 14
b = 8
a dan b = -3 dan 8

f(-2)= -2a+b=14...(1)
f(3)= 3a+b= -1...(2)

-2a+b=14
3a+b= -1
--------------- -
-5a=15
a= -3

* -a+b = -1
-(-3)+b= -1
-3+b = -1
b= 2
