If the vertex of a parabola is at (-1,5), where is the axis of symmetry?

Identify the transformations in the following function:

 $y=-2\left(x-3\right)^2-7$  

Identify the features (direction of opening, vertex, stretch or compression factor, y-intercept, max or min, domain, range) of the function and graph the function:

 $f\left(x\right)=2x^2-8x+9$
