Nilai maksimum → [tex]\tt \frac{D}{-4a} [/tex]
f(x) = x² - 3x - 17
→ [tex]\tt \frac{(-3)²-4.1.(-17)}{-4.1}[/tex]
→ [tex]\tt \frac{9 - (-68)}{-4}[/tex]
→ [tex]\tt \frac{77}{-4}[/tex]
→ [tex]\tt \bf \underline { - \frac{77}{4}} [/tex] atau -19,25
[tex]\blue{\boxed{\pink{\boxed{\orange{\star ~ \green{\mathcal{S}ilvie ~ \mathcal{R}ubia} ~ \star}}}}}[/tex]
