The foci of an ellipse are (3, 0) and (-3, 0), and the vertices are (7, 0) and (-7, 0) Find an equation of the ellipse. Then sketch the conic section and bring the sketch to your discussion section. Which form (below) does the equation of the given fit? X^2/c^2 + y/d = 1 x/c + y^2/d^2 = 1 x^2/x^2 + y^2/d^2 = 1 x^2/c^2 - y^2/d^2 = 1 y^2/sigma^2 - x^2/c^2 = 1
