. 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

ASAP (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 https://liveexample.pearsoncmg.com/test/Exercise13_21Test.txt for your code....
