Answer:
A
Step-by-step explanation:
Remember that the x-value of the vertex when an equation is given in standard form can be found with the equation . So, we can take the coefficients from the equation and plug them in.
Now we know that the x-value of the vertex is 8. Next, the equation for the y-value is , where h is the x-value of the vertex (8).
So the vertex is (8,-1).
Finally, the axis of symmetry is the x-value of the vertex, also called h.
Final answer, vertex: (8,-1) and axis of symmetry: x=8
