Answer
Focus = $(9,2)$;
Directrix $x=-3$;
Axis of symmetry $y=2$
Work Step by Step
The given parabola has general form $(y-k)^2=4p(x-h)$
Here, $4p=24 \implies p=6$ and vertex $(h,k)=(3, 2)$.
Since, the parabola is horizontal, the axis of symmetry is $y=k=2$
with focus $(h+p, k)=(3+6,2)=(9,2)$
Now, the directrix is $x=h-p=3-6=-3$
Our results are:
Focus = $(9,2)$;
Directrix $x=-3$;
Axis of symmetry $y=2$.
