Diketahui f(x)=ax+b. Tentukan bentuk fungsi fungsi berikut jika

Jawaban:

f(x) = 2x

Penjelasan dengan langkah-langkah:

[tex]f(2) = 2a + b = 4 \\ f(5) = 5a + b = 1 0 \\ - - - - - - - - - \: \: - \\ - 3a = - 6 \\ a = - 6 \div - 3 = 2 \\ [/tex]

f(2) = 4

2*2+b=4

4+b = 4

b = 4-4 = 0

a = 2 b = 0

rumus :

f(x) = 2x
