Advanced Algebra (Pre-Calculus) Conics Test Review Name _________________ Date _________ Show work for each problem. No calculator! How do you tell whether an equation represents a circle, parabola, ellipse, or hyperbola? Discuss the conic whose equation is given. Then sketch a good graph, showing the key points and lines. 1.] x 2 10 x 8 y 1 y Vertex: ________ Focus: __________ x Directrix: __________ Axis of Symmetry: _________ Endpoints of Latus Rectum: _________ _________ y 2.] 16 x 4 4 y 2 64 2 2 x Center: ________ Vertices: ______ _______ Foci: _______ _______ Length of major axis: ______ 3.] 2 x 2 2 y 2 16 x 20 y 50 0 y Center: __________ Radius: __________ x-intercept(s): ____________ x y-intercept(s): ____________ ----------------------------------------------------------------------------------------------------Determine the equation (in standard form) for each of the conics described below.
