Answer:

Step-by-step explanation:
W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form
.
We know that vertex form of parabola in form
, where (h,k) in vertex of parabola.
Upon substituting coordinates of vertex, we will get:

To find the value of a, we will substitute coordinates of point (0, -1) as:







Therefore, our required equation would be
.
