Graphing a quadratic equation using a table of values

The video tutorial explains how to graph quadratic equations by finding the line of symmetry and vertex. It demonstrates using a table of values to plot points and shows how to graph the parabola. The process involves identifying coefficients, calculating the line of symmetry, determining the vertex, and using symmetry to plot additional points. The tutorial concludes with a recap of the steps for graphing parabolas.

What is the standard form of a quadratic equation?

• Y = AX^2 + BX + C

• Y = AX^3 + BX^2 + C

• Y = AX + B

• Y = AX^2 + B

How do you calculate the line of symmetry for a quadratic equation?

• X = B / 2A

• X = -B / A

• X = -B / 2A

• X = B / A

What is the line of symmetry for the equation -3X^2 + 18X - 30?

• X = 2

• X = 3

• X = -2

• X = -3

What is the vertex of the parabola given by the equation -3X^2 + 18X - 30?

• (3, -3)

• (3, 3)
