Respuesta :
p is 3 .and its horizontal parabola it's focus is (a-p,b) so (-3,0)
Answer:
Focus of the given parabola is (-3,0)
Step-by-step explanation:
Given equation of parabola is:
y² = -12x
Standard equation of parabola is :
y² = 4px
Parabola opens right or left.
Focus of this parabola is (p,0)
y² = -12x is opens left.
y² = 4(-3)x
Here value of p = -3
So, the focus of given parabola is : (-3,0)
That's the final answer.
I hope its help you.
