An equation of an ellipse is given. x2 + 2y2- 4 (a) Find the vertices, foci, and eccentricity of the ellipse. vertex ( x , y ) = (smaller x-value) vertex ( x, y ) = (larger x-value) focus ( x, y ) = (smaller x-value) focus ( x , y ) = (larger x-value) eccentricity (b) Determine the length of the major axis. Determine the length of the minor axis. (c) Sketch a graph of the ellipse. y 10 37'F O Search Rain and snow
