Use the Vertex and the Direction in Which the Parabola $$x = - ( y - 8 ) ^ { 2 } - 1$$

Multiple Choice

Use the vertex and the direction in which the parabola opens to determine the relation's domain and range.
- $$x = - ( y - 8 ) ^ { 2 } - 1$$

A) Domain: $( - \infty , - 1 ]$
Range: $( - \infty , \infty )$
B) Domain: $( - \infty , - 1 )$
Range: $( - \infty , \infty )$
C) Domain: $( - \infty , \infty )$
Range: $( - \infty , \infty )$
D) Domain: $( - \infty , \infty )$
Range: $( - \infty ,-1)$ Is the relation a function?
