The video tutorial explains how to graph a quadratic equation in the form y = ax^2 + bx + c. It covers finding the axis of symmetry using the formula x = -b/2a, creating a table of values, calculating y-coordinates, and reflecting points over the axis of symmetry. The tutorial also discusses estimating x and y intercepts of the graph.

What is the equation we are graphing in this tutorial?

• y = x^2 + 5x + 3

• y = 3x^2 + 6x + 2

• y = 4x^2 + 2x + 5

• y = 2x^2 + 4x + 1

What is the standard form of a quadratic equation?

• y = ax^3 + bx^2 + c

• y = ax^2 + bx + c

• y = ax + b
