[Answer] The focus of a parabola is located at (0 -2). The directrix of the parabola is represented by y = 2. Which equation represents the parabola?

Answer: d. x^2 = -8y
The focus of a parabola is located at (0 -2). The directrix of the parabola is represented by y = 2. Which equation represents the parabola?

If p > 0 the parabola with equation = (opening to the right) has … The point C is located on the directrix (which is not shown to minimize clutter). The point B is the midpoint of the line segment FC. Deductions. Measured along the axis of symmetry the vertex A is equidistant from the focus F and from the directrix . According to the intercept theorem since C is on the directrix the y …

Parabola : the set of points equidistant from a fixed point ( the focus ) and a line ( the directrix ). Hyperbola: the set of points for each of which the absolute value of the difference between the distances to two given foci is a constant. Ellipse: the set of points for each of which the sum of the distances to two given foci is a constant; Oth…
