Question

Diketahui h(x)=px+q jika h(3)=-8 dan h(-2)=2 tentukan nilai fungsi h(x-2)

Answer 1

H(x) = px + q
h(3) = p(3) + q = -8
             3p + q = -8

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

h(x-2)...?

p...?
 3p + q = -8
-2p + q = 2
___________-
5p        = -10
         p = -10 : 5
         p = -2

q...?
   3p + q = -8
3(-2) + q = -8
    -6 + q = -8
            q = -8 + 6
            q = -2

h(x-2) = p(x-2) + q
          = -2(x-2) + (-2)
h(x-2) = -2x + 4 - 2
h(x-2) = -2x + 2
