The value ‘a’ in the equation is the distance from the center to a vertex of an ellipse. (The point furthest from the center). What is a The center is (-1, -2)

The horizontal ellipse equation: (x-h)^2/a^2 + (y-h)^2/b^2=1

Please help me !!! And do not put a link or ill report you, type the answer.

Me i need ! find the asymptote and determine the end behavior of the function from the graph. the asymptote of the function is= blank 1 . for very high x-values,y =blank 2 options for blank 1 x=2 x=-2 x=3 x=-3 blank 2 options moves towards negative infinity moves toward the horizontal asymptote moves toward the vertical asymptote moves toward positive infinity
