Penjelasan dengan langkah-langkah:
9] f(x) = x² - 2x + 6
a = 1; b = -2; c = 6
x = -b/(2a)
x = - (-2)/(2 . 1)
x = 1
f(1) = 1² - 2 . 1 + 6
f(1) = 5
Ordinat = 5
10] f(x) = 2 - 2x - x²
a = -1; b = -2; c = 2
x = - (-2)/(2 . -1)
x = -1
f(-1) = 2 - 2 . (-1) - (-1)²
f(-1) = 2 + 2 - 1
f(-1) = 3
Nilai maksimum = 3
