Question

Fungsi dirumuskan dengan h(x) =p x+q jika h(2)=4 dan h(3)=6.nilai h (6)

Answer 1

Cari nilai p :
( 6 - 4 ) : ( 3 - 2 ) = 2

Cari nilai q :
h(2) = 4
    4 = 2(2) + q
    q = 4 - 4
    q = 0

Sehingga,
h(6) = 2(6) + 0
       = 12

Answer 2

Pakai eliminasi aja ya
h(x) = px + q
h(2) = p.2 + q
4 = 2p + q

h(3) = 3p + q
6 = 3p + q

4 = 2p + q
6 = 3p + q
----------- -
-2 = -p
2= p

4 = 2p + q
4 = 2.2 + q
4 = 4 + q
0 = q

h(6) = 2.6 + 0 = 12
