Question

Fungsi h dinyatakan dengan rumus h(x) = ax + b jika h(5) = 16 dan h(4) = 11, nilai h(-1) adalah

Answer 1

A5+b=16
a4+b=11
----------
a =5
(5*5)+b=16
b. =16-25=-9
h(4)=(5*4)+(-9)=11 bukti

Answer 2

H(x) = ax +b
h(5) = a(5) +b = 16
       = 5a +b = 16

h(4) = a(4) +b = 11
       = 4a +b = 11

5a +b = 16
4a +b = 11 -
    a = 5

5a +b = 16
5(5) +b = 16
25 +b = 16
b = 16 -25
b = -9

h(-1) = 5(-1) +(-9)
       = -5 +(-9)
       = -14
