Suatu fungsi dinyatakan dengan rumus h(x)=3x-1,nilai h(2)+h(4) adalah

Materi : Fungsi

h(x) = 3x - 1

h(2) = 3(2) - 1
h(2) = 6 - 1
h(2) = 5

h(4) = 3(4) - 1
h(4) = 12 - 1
h(4) = 11

h(2) + h(4)
= 5 + 11
= 16

h (x) = 3x - 1
h (2) + h (4) = ...?
Jawab :
h (x) = 3x - 1
h (2) = 3.2 - 1
h (2) = 5

h (4) = 3.4 - 1
h (4) = 11

Maka,
h (2) + h (4)
= 5 + 11
= 16
