11. Fungsi h didefinisikan dengan rumus : h(x) = px + q. Jika h(2) = -11 dan h(-3) = 9, maka p + q adalah ....
a. -7
b. -1
C. 1
d. 7​

Jawaban:

h(x) = px + q

h(2) = 2p + q = -11

h(-3) = -3p + q = 9

_______________ _

5p = -20

p = -4

2p + q = -11

2(-4) + q = -11

-8 + q = -11

q = -3

2p + q = -11

2p = -8

p = -4

p + q = -7
