Nilai ekstrim dari fungsi kuadrat f(x)=x²+2x-3........adalah.......

Answer 1

Verified answer

Kelas 10 Matematika
Bab Persamaan dan Fungsi Kuadrat

f(x) = x² + 2x - 3
a = 1; b = 2; c = -3

sumbu simetri
= -b/2a
= -2/(2 . 1)
= -1

f(-1) = (-1)² + 2 . (-1) - 3
f(-1) = 1 - 2 - 3
f(-1) = -4

Nilai Ekstrim = -4
