Answer
Focus = $(-1, 0)$;
Directrix $x=1$;
Axis of Symmetry $y=0$
Work Step by Step
The equation is in the form $y^2=4px$.
Here, $4p=-4 \implies p=-1$ and vertex $(h,k)=(0,0)$
Since, the parabola is horizontal, the axis of symmetry is $y=0$
with focus $(p,0)=(-1, 0)$
Now, the directrix is $x=-p=-(-1)=1$
Our results are:
Focus $=(-1, 0)$;
Directrix $x=1$;
Axis of symmetry $y=0$.
