Question

Diketahui fungsi h(x) = px + q
Jika h(3) = -8 dan h(-2) = 2 Tentukan:
a. Nilai p dan q
b. Nilai fungsi h (-5)
c. Nilai fungsi h (x-2)
d. Nilai m jika h (m)= -14 ?

Answer 1

H(3) = 3p + q = -8
h(-2)= -2p + q = 2
________________ -
5p = -10
p = -2
q = -2
H( x) = -2x -2
h(-5) = 10-2 =8
H (x-2) = -2(x-2) -2
= -2x +4 -2
= -2x + 2
h(m) = -2m -2 = -14
-2m = -12
m = 6
