Question

Suatu fungsi linear dengan f(x) = a× +1 dan f(6) = 4. tentukan bentuk fungsinya ?

Answer 1

F(x) = ax + 1 f(6) = 4 6a + 1 = 4 6a = 3 a = 3/6 = 1/2 Rumus fungsi f (x) = 1/2 x + 1

Answer 2

Jika f(x) = ax+1
maka f(6)= 4

a(6)+1=4
6a+1=4
6a=4-1
6a = 3
a = 3/6
a = 0,5

f(x) = ax+1
f(6)  =(0,5)(6)+1 =
           3 + 1 = 4
