Answer:
y - 2 = -(x + 4)
Step-by-step explanation:
A max at (-4, 2) could very well be the vertex (as well as the max) of a parabola that opens down. The vertex form of a parabola is:
y - k = a(x - h), where (h, k) is the vertex or maximum.
Given that our max is at (-4, 2), write: y - 2 = -(x + 4), with that " - " sign stemming from the fact that the parabola opens down.
