Answer:
Axis of symmetry:

Vertex:

Step-by-step explanation:
The given quadratic equation is

By comparing to the general quadratic function;

We have a=4,b=5,c=-1
The equation of the axis of symmetry is given by the formula;

We got this formula by completing the square on the general quadratic function.
We substitute a=4 and b=5 to obtain;


is the axis of symmetry.
To find the y-value of the vertex, we put

into the function to obtain;



The vertex of the given function is
