Question

Parabola yang mempunyai koordinat puncak (1,-4)dan melalui titik (3,4)adalah...

Answer 1

Titik puncak = (1,-4)
a = 1
b = -4
HORIZONTAL
x = a - p
3 = 1 - p
p = 1 - 3
p = -2
pers.
= 4p (x - a)
= 4(-2) (x-1)
+ 8y + 16 = -8x + 8
+ 8y + 8x +8 = 0

VERTIKAL
y = b - p
4 = -4 -p
p = -8
pers
= 4p (y-b)
= 4(-8) (y-4)
- 2x +1 = -32y + 128
- 2x +32y - 127 = 0

smg bermanfaat , maaf klo slah^^
