i) Find \( A^{-1}\left(\begin{array}{ll}3 & 2\end{array}\right) \) ii) Find the product \( A^{-1}\binom{3}{5} \) iii) Given that \( \binom{x}{y}=A^{-1}\binom{3}{5} \), write down the values of \( x \) and \( y \).

Decide whether or not the equation has a circle as its graph. If it does, give the cent and the radius. If it does not, describe the graph. \( x^{2}+y^{2}+8 x+4 y+16=0 \) A. The graph of the equation is a line. B. The graph of the equation is a point. C. The graph of the equation is a circle with center \( \square \). (Type an ordered pair D. The radius of the circle is \( \square \). D. The graph is nonexistent.
