Definition and Equation of a Parabola with Vertical AxisA parabola is the set of all points M(x,y)M(x,y) in a plane such that the distance from MM to a fixed point FF called the focus is equal to the distance from MM to a fixed line called the directrix as shown below in the ...
In the equation above, a, b and c are constants, and a is not equal to zero. (If a were zero, you would have a linear equation.) Through this equation, you can identify the vertex, axis of symmetry and the direction in which the parabola opens. Example With Step-by-Step Instruction...
