Answer:
Axis of symmetry: x = 2
Vertex at: (2, -13)
y-intercept is (0, -5)
Step-by-step explanation:
The equation for the x-value of the vertex in a quadratic of the form:

is given by:

which in our case gives:

Then the equation for the axis of symmetry is given by: x = 2
and the y of the vertex can be calculated as:

Then the vertex is at the point: (2, -13)
And the y-intercept is found when x=0, that is:
y-intercept is (0, -5)
