If you have any confusion regarding the answer please ask and
rate ?
A. Write an equation of a parabola with the given vertex and
focus: vertex(2,4) and focus (2,5)
B. Write an equation for the parabola with a vertex (-1,5) and
directrix x=-15
. Put the equation into the standard form of a parabola and find
the vertex, focus, and directrix (needs to be an equation of a
line). The standard form of a parabola can be found in Section 7.3
of the textbook. Answers must be exact values and not
approximations. 4y2 + 2 = -x + 8y
A. Standard form
B.Vertex
C.Focus
D.Directrix
What is the standard form of the equation of the parabola with
the focus (−1,3) and the directrix x=9?
Select the correct
answer below:
a) (x+1)2=−12(y−6)
b) (y−3)2=−20(x−4)
c) (x−9)2=8(y−1)
d)(y−3)2=20(x−4)
please show work and what is the correct answer? thanks

(Algebra: vertex form equations) The equation of a parabola can
be expressed in either standard form (y = ax^2 + bx + c) or vertex
form (y = a(x-h)^2 + k). Write a program that prompts the user to
enter a, b, and c as integers in standard form and displays h and k
in the vertex form. Hint: Use the Rational class in LiveExample
13.13 for computing h and k. Use the template at
