Penjelasan dengan langkah-langkah:
Nilai Mnimum Fungsi
y = (x-16)(x-14)(x+16)(x+14)
y = (x² - 256)(x² - 196)
y = x⁴ - 452x² + 256 × 196
syarat minimum/maksimum → y' = 0
4x³ - 904x = 0
x² = 226
y min
= 226² - 452.226 + 256.196
= (16 × 14)² - 226²
= (16 × 14 - 226)(16 × 14 + 226)
= (224 - 226)(224 + 226)
= -2 × 450
= -900
