Question

Tentukan nilai p dan q
1. F(x)=px-q.sedangkan f(3)=4 dan f (-5)=-28
Pliss djawab dgn caranya butuh kali

Answer 1

F(x)=px-q
f(3) = 4
p(3)-q = 4
3p - q = 4

f(-5) = 28
p(-5) - q = 28
-5p - q = 28

3p - q = 4
-5p - q = 28
dieliminasi
8p = -24
p = -3

3p - q = 4
3(-3) - q = 4
-9 - q = 4
-q = 13
q = -13

Answer 2

F(x) = Px - Q, F(3) = 3P - Q = 4 F(-5) = -5P -Q = -28 ________________- 8P = 32 P = 4 3P - Q = 4 3(4) - Q = 4 12 - Q = 4 Q = 8 Jika kurang jelas bisa dilihat di gambar :)
