Verified answer
F(x) = 3(x - 1)² + 5f(x) = 3(x² - 2x + 1) + 5
f(x) = 3x² - 6x + 3 + 5
f(x) = 3x² - 6x + 8
Format :
f(x) = ax² + bx + c
Maka
a = 3 , b = -6 , c = 8
a + b + c = 3 - 6 + 8 = 5

Bentuk pers. kuadrat adalahax² + bx + c = 0
f(x) = 3(x-1)² + 5
f(x) = 3 (x² - 2x + 1) + 5
f(x) = 3x² - 6x + 3 + 5
f(x) = 3x² - 6x + 8
a = 3
b = -6
c = 8
jadi a + b + c
= 3 + (-6) + 8
= 5
