Answer:
vertex = (- 3, 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - 4(x + 3)² + 2 ← is in vertex form
with (h, k ) = (- 3, 2 )
Answer:
So for this problem, we can use the formular:
(A + B)² = A² + 2AB + B²
Our orginal expression is: (x + 4)². In this expression, A can be written as x, B represents for 4, that leads to our answer:
(x + 4)² = x² + 2 . 4x + 4² = x² + 8x + 16
The correct answer will be D
