Discussion:
Q1. Given the equation of the parabola( x^2)+4x-8y+4=0
(a)Write the equation in standard form
(b)Find the coordinates of the vertex, focus and equation of the directix.
Q2. Given the equation of the ellipse (9x^2)+(4y^2)-36x+8y+31=0 in standard form and find the center, foci, and vertices.
Sketch the graph clearly labeling the coordinates of all important points. What are the lenghts of the major and minor axes?
