Identify the forms of quadratic equations.

• Vertex Form

• Factored Form (Intercept Form)

• Standard Form

Match the following equations with their correct form.

• Quadratic Formula

• f(x) = a(x - h)² + k

• Factor Form

• f(x) = ax² + bx + c

• Vertex Form

• f(x) = a(factor)(factor)

• Standard form of a quadratic equation

When you rewrite a quadratic equation in the following form. It is written in ________ form

• Vertex Form

• Standard Form

• Quadratic Form

• Factored Form

Match the following forms of equations with their correct descriptions.

• Standard form of a quadratic equation

• y = ax² + bx + c

• Vertex form of a quadratic equation

• y = mx + b

• Slope-intercept form of a linear equation

• y = a(x - h)² + k

Answer explanation

The correct choice is y = a(x - h)^2 + k, which represents the vertex form of a quadratic equation with the vertex at (h, k).

Which form of the quadratic equation shows the transformations most clearly?

• Function Notation

• Standard Form

• Vertex Form

• Factored Form
