L(x) = 8x - 2x²
Manfaatkan titik simetri:
x = - 8 / (2. (-2))
x = -8 / -4
x = 2
Substitusikan x = 2
L(2) = 8(2) - 2(2)²
L(2) = 16 - 2(4)
L(2) = 16 - 8
L(2) = 8 satuan luas [Max] [A]
Nomor 5.
Memotong sumbu y ketika x = 0
Substitusikan x = 0 pada f(x) akan menghasilkan ordinat = -12
Sehingga, titiknya adalah (0,-12) [B]
