yes, because there is a lot of variability in the grammar book data.
The vertex is at (4, -49) and the axis of symmetry is at x= 4.
To find the vertex of this equation, use this method:

a=2
b=-16
This will help get your x value and the axis of symmetry. To find the y value of the vertex, insert the x value, 4 to get your y value, -49.
Answer:
x = -16
