Focus of parabola
WebGiven the focus and the directrix of a parabola, we can find the parabola's equation. Consider, for example, the parabola whose focus is at ( − 2 , 5 ) (-2,5) ( − 2 , 5 ) left parenthesis, minus, 2, comma, 5, right parenthesis and directrix is y = 3 y=3 y = 3 y, equals, 3 . WebThe focus of a parabola can be found by adding to the x-coordinate if the parabola opens left or right. Step 5.2 Substitute the known values of , , and into the formula and simplify.
