Step-by-step explanation:
Hi there!
Because we're given the vertex of the parabola, we can determine its equation in vertex form:
where the vertex is
Plug in the vertex (0,0)
Now, we must solve for a. Plug in the given point (-2,3) and solve for a:
Therefore, the value of a is . Plug this back into :
I hope this helps!
