Amatilah gambar berikut!​

Answer 1

Penjelasan dengan langkah-langkah:

diketahui :

xₚ = 3

yₚ = -1

x = 0

y = -4

y = a(x - xₚ)² + yₚ

-4 = a(0 - 3)² - 1

-4 = 9a - 1

9a = -4 + 1

9a = -3

a = -3/9

a = -1/3

y = -1/3(x - 3)² - 1

y = -1/a (x - b)² - c

a = 3 ; b = 3 ; c = 1

a + b + c

= 3 + 3 + 1

= 7
