\begin{gathered} \text{The given equation is,} \\ y=-x^2-4x-1 \\ \text{The general quadratic equation is,} \\ y=ax^2+bx+c \\ Compare\text{ both the equation,} \\ So, \\ a=-1 \\ So,\text{ a is negative(-)} \\ \text{Thus the opening will be in downward direction.} \\ \text{The last option is true.} \\ \text{Negative:Down} \end{gathered}
