Determine the vertex and axis of symmetry

Question

Determine the vertex and axis of symmetry on this graph. The coordinates given are (-1/2, -9/4) I will try to attach a photo. I have no idea how to solve this please help

Answer 1

if (-1/2 -9/4) is the vertex

the parabola's equation is y =a(x +1/2)^2 - 9/4

with axis of symmetry as x= -1/2
