koordinat titik puncak grafik fungsi kuadrat
f(x)=x²-4x+1 adalah​

Jawab:

Penjelasan dengan langkah-langkah:

koordinat puncak

[tex]f(x) = x^{2} - 4x + 1[/tex]

a = 1

b = -4

c = 1

[tex]xp =- \frac{b}{2a} \\xp = -\frac{-4}{2} \\xp = 2\\\\yp = - \frac{D}{4a}\\D = b^{2} - 4ac\\D = (-4)^{2} - 4\\\\D = 12\\yp = -\frac{12}{4}\\yp = -3[/tex]

(xp, yp) = (4, -3)

semoga jawabannya membantu
