What is the equation of a parabola with vertex (3, 4) and focus (7, 4)?

16(x - 3) = (y - 4)2

28(x - 3) = (y - 4)2

-28(x - 3) = (y - 4)2

-16(x - 3) = (y - 4)2

Find the equation of the parabola with vertex (4,6) and focus (4,9).

(x-4)2 = 12(y - 6)

(x-4)2 = 3(y - 6)

(y-6)2 = 3(x-4)

(y-6)2 = 12(x-4)

The focus is at (2,0) and the vertex is at (-4,0).  What is the equation of the parabola?

y2 = 24(x+4)

(y+4)2 = -12x

x2 = 16(y+4)

(x+4)2  = -20y

A hyperbola has vertices (±5, 0) and one focus at (6, 0). What is the equation of the hyperbola in standard form?

x²/25 + y²/11 = 1

x²/5 - y²/11 = 1

x²/11- y²/25 = 1

x²/25 - y²/11= 1

Find the equation of the parabola with vertex (5,1) and Focus (2,1).

(y−1)2=12(x−5)(y-1)^2=12(x-5)

(y+1)2=−12(x+5)(y+1)^2=-12(x+5)

(y−1)2=−12(x−5)(y-1)^2=-12(x-5)

(x−5)2=−12(y−1)(x-5)^2=-12(y-1)
