From Latin:

**vertex**"highest point" Definition: The common endpoint of two or more rays or line segments.**Vertex**typically means a corner or a point where lines meet. For example a square has four corners, each is called a**vertex**. The plural form of**vertex**is vertices.Moreover, what is the formula for Vertex?

The

**vertex**form of a quadratic is given by. y = a(x – h)^{2}+ k, where (h, k) is the**vertex**. The "a" in the**vertex**form is the same "a" as. in y = ax^{2}+ bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down.How do you find the vertex in algebra?

**To do so, we use the following steps:**

- Get the equation in the form y = ax2 + bx + c.
- Calculate -b / 2a. This is the x-coordinate of the vertex.
- To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

How do you find the vertex and the axis of symmetry?

The

**axis of symmetry**always passes through the**vertex**of the parabola . The -coordinate of the**vertex**is the**equation**of the**axis of symmetry**of the parabola. For a quadratic function in standard form, y = a x 2 + b x + c , the**axis of symmetry**is a vertical line x = − b 2 a .
