Answer:
B
Explanation:
The graph has zeros at x = - 2 and x = - 6, thus
the factors are (x + 2) and (x + 6)
The function is the product of its factors, thus
y = a(x + 2)(x + 6) ← where a is a multiplier
Let a = 1 and expand the factors
y = x² + 6x + 2x + 12 ( collect like terms )
y = x² + 8x + 12 → B
