MA1310: Module 5 Vectors and Conic SectionsExercise 5.2Graphing Ellipse, Hyperbola, and ParabolaAnswer the following questions to complete this exercise:1. Describe an ellipse in two sentences.2. Find the standard form of the equation of the ellipse and give the location of its foci.The standard form of the equation of an ellipse with the center at the origin and major and minoraxes of lengths 2a and 2b (where a and b are positive, and a2 > b2) is:x2 y21a2 b2orx2 y21b2 a2The location of foci are at (–c, 0) and (c, 0) where c2 = a2 – b2.3. Graph the ellipse.a.1(x 2)2 (y 1)21 and choose the correct graph from the given graphs:94MA1310: Module 5 Vectors and Conic SectionsExercise 5.2Graphing Ellipse, Hyperbola, and Parabolab.c.d.2MA1310: Module 5 Vectors and Conic SectionsExercise 5.2Graphing Ellipse, Hyperbola, and Parabola[Hint: To graph this ellipse, find the center (h, k) by comparing the given equation with the standardform of equation centered at (h, k). Next, find a and b. Find the vertices (h – a, k) and (h + a, k). Findthe foci (h + c, k) and (h – c, k).]4.
