Answer:
Step-by-step explanation:
The vertex form of the equation of a parabola is:
Where (h,k) is the vertex.
To obtain this form, we need to complete the square:
Move the 3 to the other side of the equation:
Add this value to both sides of the equation:
Then, rewriting:
Finally, we must solve for "y", getting the equation of the parabola in vertex form:
