Question

Pada fungsi g(x) = px + q. jika g(3) = -1 dan g(5) = 4, maka nilai dari g(11) =

Answer 1

Verified answer

Jawab

g(5) = 4
g(3) = -1...(-)
(5-3)p = 4-(-1)
2p = 5
p= 5/2


g(5) = 4
q = 4 -5p
q = 4 - 5(5/2)
q = - 17/2

g(x)  = 5/2 p - 17/2
g(x)= 1/2 (5p - 17)
g(11) = 1/2 (55 -17)
g(11) = 19
