How do you find the vertex of a parabola in standard form?
In this equation, the vertex of the parabola is the point (h,k) . You can see how this relates to the standard equation by multiplying it out: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k . This means that in the standard form, y=ax2+bx+c , the expression −b2a gives the x -coordinate of the vertex.
What is the axis of symmetry of a parabola calculator?
The axis of symmetry is the line perpendicular to the directrix that passes through the vertex and the focus: x = 2. The focal length is the distance between the focus and the vertex: \frac{1}{4}.
How do you convert standard form to standard form?
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
How do you find the standard form of a parabola?
If a parabola has a vertical axis, the standard form of the equation of the parabola is this: (x – h)2 = 4p(y – k), where p≠ 0. The vertex of this parabola is at (h, k). The focus is at (h, k + p). The directrix is the line y = k – p.
How do you find the equation of a parabola with the vertex?
We can use the vertex form to find a parabola’s equation. The idea is to use the coordinates of its vertex (maximum point, or minimum point) to write its equation in the form y=a(x−h)2+k (assuming we can read the coordinates (h,k) from the graph) and then to find the value of the coefficient a.
What is the standard form of a parabola calculator?
The standard form of a quadratic equation is y = ax² + bx + c . You can use this vertex calculator to transform that equation into the vertex form, which allows you to find the important points of the parabola – its vertex and focus.
How do you find the standard form of a parabola with the vertex and focus?
The standard form is (x – h)2 = 4p (y – k), where the focus is (h, k + p) and the directrix is y = k – p. If the parabola is rotated so that its vertex is (h,k) and its axis of symmetry is parallel to the x-axis, it has an equation of (y – k)2 = 4p (x – h), where the focus is (h + p, k) and the directrix is x = h – p.
