3.
f(x) = 5 - 6x - x²
f(x) = -(x² + 6x) + 5
f(x) = -(x² + 6x + 9) + 5 + 9
f(x) = -(x + 3)² + 14
p = 3
q = 14
Jawaban C
___________________________
4.
f(x) = ax² + bx + c
a = -1
b = 1
c = 3
maka
f(x) = -x² + x + 3
f(x) = 3 + x - x²
Jawaban B

5.
Opsi D
f(x) = 7 - 5x - 2x²
a = -2
b = -5
c = 7
a + b + c
= -2 + (-5) + 7
= -7 + 7
= 0
