From the given equation, the parabola is symmetric about x - axis and it is open right ward. , so the vertex is at
If you have any feedback about our math content, please mail us : You can also visit the following web pages on different stuff in math. The red point in the pictures below is the focus of the parabola and the red line is the directrix.As you can see from the diagrams, when the focus is above the directrix Example 1, the parabola opens upwards. You can either use the parabola calculator to do it for you or you can use the equation.
Find the equation of the parabola if the vertex is (4, 1) and the focus is (4, â 3), From the given information the parabola is symmetric about y -axis and open downward, Find the equation of the parabola if the vertex is (0, 0) and the focus is (0, â 4), Find the equation of the parabola if the vertex is (1, 4) and the focus is (-2, 4), From the given information the parabola is symmetric about x -axis and left downward.
A parabola is a locus of points equidistant from both 1) a single point, called the focus of the parabola, and 2) a line, called the directrix of the parabola. h,k+ .
1 The parabola equation in vertex form. (y − 2) = 3 (x − 5) 2 foci 3x2 + 2x + 5y − 6 = 0 vertices x = y2 axis (y − 3) 2 = 8 (x − 5) ... Parabola equation and graph with major axis parallel to y axis. Find the focus, vertex, equation of directrix and length of the latus rectum of the parabola. ) ... Graph. The coordinates of the focus are By applying these values in the standard form we will get the equation of the required parabola.
, so the vertex is at the origin.
If the major axis is parallel to the x axis, interchange x and y during your calculation. This Parabola equation solver calculator helps you to solve your academic equations and engineering algebraic problems with ease.
Explore how the focus and directrix relate to the graph of a parabola with the interactive program below. x All you have to do is to use the following equations: y₀ = c - (b² - 1)/(4a) = -4 - (9-1)/8 = -5, y = c - (b² + 1)/(4a) = -4 - (9+1)/8 = -5.25, If you're looking for a parabola with a horizontal orientation, check the, Check out 23 similar coordinate geometry calculators , How to use the parabola equation calculator: an example, Enter the coefficients a, b and c of the standard form of your quadratic equation.
