Question

Suatu fungsi h(×)=a×+b.jika h(4)=-16 dan h(-4)=0,mka nilai dari 4a-b...........

Answer 1

Answer 2

H(x) = ax + b
h(4) = a(4) + b
 -16 = 4a + b

 h(x) = ax + b
h(-4) = a(-4) + b
     0 = -4a + b

-16 = 4a + b
   0 = -4a + b 
-16 = 8a
  -2 = a

 0 = -4a + b
 0 = -4(-2) + b
 0 = 8 + b
-8 = b

4a - b = 4(-2) - (-8)
         = -8 - (-8)
         = -8 + 8
         = 0

Jadi nilai 4a - b adalah 0.
