Question

Suatuu fungsi g ditentukan oleh aturan g(x)=px+q, jika g(2)=3 dan g(-1)=6, maka rumus fungsi g adalah...???

Answer 1

G(x) = px +q
g(2) = 2p + q = 3
g (-1)= -p + q = 6
---------------------------- -
     3p = -3
     p =-1
-p + q = 6
-(-1) + q = 6
1 + q = 6
q = 5
maka fungsi g(x) = -x + 5

Answer 2

G(x)=px+q
g(2)=2p+q = 3
g(-1)= -p+q = 6
----------------- -
3p=-3
p=-1

-p+q=6
1+q=6
q=5

g(x)=-x+5
