Answer:
The equation of parabola is given by :
Step-by-step explanation:
Given that vertex and focus of parabola are
Vertex: (4,-3)
Focus:(,-3)
The general equation of parabola is given by.
, When x-componet of focus and Vertex is same
, When y-componet of focus and Vertex is same
where Vertex: (h,k)
and p is distance between vertex and focus
The distance between two points is given by :
L=
For value of p:
p=
p=
p=
p= and p=
Since, Focus is left side of the vertex,
p= is required value
Replacing value in general equation of parabola,
Vertex: (h,k)=(4,-3)
p=
Answer:
2)
collect like terms
move the constant to the right hand side and change its sign.
Subtract the numbers
Divide both sides of the equation by 8
