q. - x -
f(x) = x² - x × 1 + 4 ÷ 1
f(2) = ?
f(x) = x² - x × 1 + 4 ÷ 1
f(2) = ?
Jawaban:
f(x) = x² - x × 1 + 4 ÷ 1
f(2) = 2² - 2 × 1 + 4 ÷ 1
f(2) = 4 - 2 × 1 + 4 ÷ 1
f(2) = 2 × 1 + 4
f(2) = 6✔
Jawaban:
6
Penjelasan dengan langkah-langkah:
f(x) = x² - x × 1 + 4 ÷ 1
f(2) = 2² - 2 × 1 + 4 ÷ 1
f(2) = (2.2) - (2.1) + 4/1
f(2) = 4 - 2 + 4
f(2) = 2 + 4
f(2) = 6
