Learn how to write the equation of a parabola given the vertex and point

The video tutorial explains how to use the vertex form of a quadratic equation to find the equation of a parabola given a vertex and a point. It covers identifying the vertex as coordinates H and K, and a point as X and Y. The instructor demonstrates plugging these values into the vertex form equation, simplifying it, and solving for the variable 'a'. The final equation is derived for any point on the parabola, emphasizing the importance of understanding the vertex form and its components.

What do the coordinates H and K represent in a quadratic equation?

• The axis of symmetry

• The roots of the equation

• The vertex of the parabola

• The slope and intercept

How are points represented in the context of a quadratic equation?

• As X and Y coordinates

• As slopes

• As distances

• As angles

Which form of the quadratic equation is used to substitute the values of H, K, X, and Y?

• Vertex form

• Factored form

• Intercept form

• Standard form

What is the result of squaring a negative number, such as -2?

• -4

• 0

• 4

• 2

What is the final form of the quadratic equation derived in the tutorial?

• y = 2x + 1

• y = 2(x - 2)^2 + 1

• y = x^2 + 2x + 1

• y = 2x^2 - 4x + 1
