pada fungsi 6: x px + q.. diketahui G(3) =5 dan G(1) = -3 , hitunglah nilai p dan q , dan bentuk fungsinya

G(x) = px + q
G(3) = p(3) + q = 5 .... 3p + q = 5
G(1) = p(1) + q = - 3 .... p + q = - 3

..
3p + q = 5
p + q = - 3
-------------- --
2p = 8
p = 8/2
p = 4

3p + q = 5
3(4) + q = 5
12 + q = 5
q = 5 - 12
q = - 7

G(x) = px + q
G(x) = 4x - 7
