GAN TOLONG DI BANTU GAN BESOK DI KUMPULKAN

f(x)= ax+b

a. f(1)= 1a+b= 3
f(2) 2a+b= 5
------------------- --
-1a= -2 -> a= 2

1a+b= 3 -> 1.2+b= 3
b= 3-2 -> b= 1


b. f(0)= 0a+b= -6
f(3)= 3a+b= -5
------------------------- --
-3a= -1 -> a= 3

0a+b= -6 -> 0.3+b= -6
b= -6



maap kalo salah

bantu lengkapin.

diketahui f(x) = ax+b

maka,
C. f(2)=3 dan f(4)=4

4a+b=4
2a+b=3 -
2a = 1
a =½

4.½+b=4
2 + b = 4
b = 4-2
b = 2
