the third option
Step-by-step explanation:
Our equation is
Equation of a vertical parabola is
where (h,k) is the center
The focus is
(h+p, k)
Equation of directrix is
x= h-p,
Here the center is (10,0)
Next, we factor out 4 in the original equation
So we have
So our p=9,
So our focus is
(10+9,0) or (19,0)
The third option is the answer
