The vertex form calculator that helps you to find the vertex of a parabola and the vertex form of a quadratic equation. With that, the calculator quickly displays vertex and y-intercept points with a graph.
The vertex form of a parabola is a point or place where it turns. If the quadratic function converts to vertex form, then the vertex is (h, k).
The vertex equation is
\(y = a(x – h)^2 + k\)
“The point at the intersection of the parabola and its line is a symmetry known as the vertex of the parabola”.
The vertex of a parabola is a specific point that represents the different values of the quadratic curve. The vertex can be either maximum (when parabola going downward) or minimum (when parabola going up). Therefore, the vertex form is the intersection of a parabola with its symmetric axis.
Normally, the vertex is (h, k), where h indicates the x-coordinates, and k stands for y-coordinates.
A standard form of a parabola \( ax^2 + bx + c \), so we can use quadratic equations of the vertex coordinates:
\(h = -b / 2a\)
\(k = c – b^2 / 4a\)
However, an Online Parabola Calculator helps to find the standard form and vertex form of a parabola equation for the given values.
Finding the vertex of a parabola for the equation:
\(= 2(x – (-6))^2 – 13\)
According to given equation
Vertex form is:
\(y = 2 (x + 6)^2 – 13\)
Standard form of given equation is:
\(y = 2 x^2 + 24 x + 59\)
Characteristic Points are:
\(Vertex = P (-6, -13)\)
\(Y-intercept = P (0, 59)\)
Also, the parabola vertex calculator can display a parabola graph with exact values when you substitute the same values for a vertex form equation.
The standard form of a quadratic equation is \(ax^2 + bx + c=0\), where m and x are variables and a, b, and c are the coefficients. It is simple to solve an equation when it is in standard form because we calculate the answer with a, b, and c.
The process is smooth when the equation is in vertex form. The standard to vertex form of a quadratic equation is \(Q = m(x – h)^2 + K\), where m represents the slope. If you want to get vertex from the standard form, follow these points:
However, an Online Slope Calculator helps to find the slope (m) or gradient between two points in the Cartesian coordinate plane.
The vertex form calculator can convert vertex form to the standard form of a parabola. If you want to know how to change the vertex to standard form, let’s start!
