CORRECT Answers
Conic Sections - CORRECT ANSWER - Consists of four geometric shapes (parabolas,
circles, ellipses, and hyperbolas) that are actually the cross-sections of a right circular cone sliced
by a plane


If A equals B - CORRECT ANSWER - It's a circle



If A doesn't equal B (same signs) - CORRECT ANSWER - It's an ellipse



If A doesn't equal B (different signs) - CORRECT ANSWER - It's a hyperbola



General Form - CORRECT ANSWER - A x2 + B y2 + C x+ D y + E = 0



Parabola - CORRECT ANSWER - Is the set of points on the coordinate plane that are
equidistant from a fixed point (focus) and fixed line (directrix)


Parabola's Standard Form (x2) - CORRECT ANSWER - y = a ( x - h) 2 + k



Parabola's Standard Form (x2): vertex - CORRECT ANSWER -(h,k)



Parabola's Standard Form (x2): focus - CORRECT ANSWER -(h,k+c)



Parabola's Standard Form (x2): axis of symmetry - CORRECT ANSWER -(x=h)



Parabola's Standard Form (x2): directrix - CORRECT ANSWER -(y=k-c)
