Materi : Fungsi LinearKelas : VIII SMP
Kategori : Matematika
Pembahasan :
g(x) = px + q
g(2) = 2p + q = 7
g(-3) = -3p + q = 2
——————————— (-)
5p = 5
p = 1 → q = 5
Rumus Fungsinya...
G(x) = px + q
G(x) = x + 5
g(2)=7
g(-3)=2
dit:rumus fungsi?
jwb:g(2)=2p+q=7
g(-3)=-3p+q=2
--------------------- --
5p=5
p=1
2p+q=7
2.1+q=7
q=7-5=2
jadi rumus fungsinya adalah g(x)=x+2
