Answer
Opens to the left
Work Step by Step
The direction of the opening of the parabola is determined by the sign of the coefficient of the squared term and whether the squared term is $x$ or $y$.
If the equation is in the form:
$y=ax^2+bx+c$, $\gt0 \longrightarrow $ Opens up
$y=ax^2+bx+c$, $\lt0 \longrightarrow $ Opens down
$x=ay^2+by+c$, $\gt0 \longrightarrow $ Opens right
$x=ay^2+by+c$, $\lt0 \longrightarrow $ Opens left
Using these rules, we get the parabola to open to the left.
