Learn two different ways to find the vertex and axis of symmetry

The video tutorial explains two methods to find the vertex and axis of symmetry of a parabola. The first method uses the formula X = -B/2A to find the axis of symmetry and then calculates the vertex. The second method involves completing the square to rewrite the equation in vertex form. The tutorial also covers how to determine if the vertex is a maximum or minimum point by analyzing the graph's direction based on the coefficient A. The domain and range of the parabola are discussed, concluding with the vertex at (-1, -1) and a range from -1 to infinity.

What is the formula to find the axis of symmetry for a quadratic equation in standard form?

• X = B / 2A

• Y = -B / 2A

• Y = B / 2A

• X = -B / 2A

When completing the square, what is the first step to rewrite a quadratic equation in vertex form?

• Subtract the linear term from both sides

• Multiply the equation by 2

• Factor out the leading coefficient from the quadratic and linear terms

• Add the constant term to both sides

Which method is more suitable if you are comfortable with algebraic manipulation?

• Using a calculator

• Using the formula X = -B / 2A

• Completing the square

• Graphing the equation

How can you determine if the vertex of a parabola is a maximum or minimum point?

• By checking the sign of the coefficient B

• By checking the sign of the coefficient A
