Final answer:
The vortex, axis of symmetry, minimum value, domain, and range of the function y = -5(x+2)^2 -8 are (-2, -8), x = -2, -8, All Real Numbers, and (-8, [infinity]) respectively.
Step-by-step explanation:
The vortex of the equation y = -5(x+2)^2 -8 is the point (-2, -8). The axis of symmetry is the vertical line x = -2. The equation represents a quadratic function with a vertex at the vortex point, so it opens downwards and has a minimum value. In this case, the minimum value is -8. The domain of the function is all real numbers, and the range is (-8, [infinity]).
