Answer:
y = (x +2)² -3
Step-by-step explanation:
You want the math operators that are needed to properly write the equation of the given parabola in vertex form.
Vertex
The vertex is the low point on the curve. Its coordinates are (-2, -3).
Vertex form
The vertex form of the equation for a parabola is ...
y = a(x -h)² +k
You want the equation for (h, k) = (-2, -3). It is ...
y = a(x +2)² -3
The operators are plus (+) and minus (-).
