Answer:
(a) y < 3(x +2)² +2
Explanation:
You want to know the inequality representing the region less than the quadratic with vertex (-2, 2) and containing the point (-4, 14).
Vertex form
The vertex form equation for a quadratic with vertex (h, k) and some scale factor 'a' is ...
y = a(x -h)² +k
For the given vertex (-2, 2), the boundary line equation is ...
y = a(x -(-2))² +2 = a(x +2)² +2
Scale factor
The value of 'a' is positive when the curve opens upward.
Here, the point (-4, 14) has a y-value greater than that of the vertex, so we know the curve opens upward (a > 0).
The only reasonable answer choice is ...
y < 3(x +2)² +2
