The vertex is (-5, -5)

this is the lowest point found, the way to figure this out is to graph it or take the derivative

The derivative is 2x + 10 = 0

x = -5

The axist of symmetry is also -5 because it runs through the vertex.

The direction of opening is concave upward. this is because the x value is positive.
