Learn how to graph a quadratic using the axis of symmetry and table of values

The video tutorial explains how to work with quadratic equations, starting with identifying the standard form and coefficients A, B, and C. It then covers finding the axis of symmetry and the vertex, followed by graphing the quadratic equation. The tutorial also discusses choosing points for plotting and completing the graph by reflecting points across the axis of symmetry.

What is the standard form of a quadratic equation?

• Y = AX^2 + BX + C

• Y = AX + B^2 + C

• Y = MX + B

• Y = A + BX + CX^2

How do you find the axis of symmetry for a quadratic equation?

• X = B / 2A

• X = -B / 2A

• X = A / 2B

• X = -A / 2B

What is the X-coordinate of the vertex if B = -8 and A = 2?

• 4

• 2

• -2

• -4

What is the Y-coordinate of the vertex if X = 2 for the equation Y = 2X^2 - 8X - 2?

• -10

• 0

• 10

• -8

When graphing a quadratic equation, why might you choose points to the left of the vertex?

• They are more accurate.

• They are always negative.

• They are easier to calculate.

• They are always positive.

What is the Y-coordinate when X = 1 for the equation Y = 2X^2 - 8X - 2?

• 0

• -2

• -6

• -8

How do you complete the graph of a quadratic equation after plotting points?

• Draw a straight line through the points.

• Reflect the points over the axis of symmetry.

• Connect the points with a dashed line.

• Plot additional points randomly.
