How do I find a quadratic equation given 2 points and no vertex?

How do I find a quadratic equation given 2 points and no vertex?

How do i find the equation of a parabola given 2 points and the axis of symmetry, but no vertex?

Using the vertex form of a parabola f(x) = a(x – h)2 + k where (h,k) is the vertex of the parabola.
The axis of symmetry is x = 0 so h also equals 0.
a = 1.
Substituting the a value into the first equation of the linear system:

How do you write a quadratic function in vertex form with given points?

Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.
The vertex of a parabola is the point at the top or bottom of the parabola.
'h' is -6, the first coordinate in the vertex.
'k' is -4, the second coordinate in the vertex.
'x' is -2, the first coordinate in the other point.

How do you find the vertex given two points?

To find the vertex of a parabola, you first need to find x (or y, if your parabola is sideways) through the formula for the axis of symmetry. Then, you'll use that value to solve for y (or x if your parabola opens to the side) by using the quadratic equation. Those two coordinates are your parabola's vertex.

What is the equation for two points?

The two-point form of a line is used for finding the equation of a line given two points (x1,y1) ( x 1 , y 1 ) and (x2,y2) ( x 2 , y 2 ) on it. The two point-form of a line is:y−y1=y2−y1x2−x1(x−x1) y − y 1 = y 2 − y 1 x 2 − x 1 ( x − x 1 ) OR y−y2=y2−y1x2−x1(x−x2) y − y 2 = y 2 − y 1 x 2 − x 1 ( x − x 2 ) .
