Algebra II Recipe: Graphing a Quadratic Equation

By C Adams

Directions and/or Common Information:

How do the graphs of the following equations differ from the graph of y = x2?

y = 3x2 - 7

y = -x2 + 3

  

Directions and/or Common Information:

Find the vertex and the equation of the axis of symmetry for the graph of each quadratic equation.

y = -2(x - 2)2 + 4

y = (x - 4)(x + 2)

y = -3x2 + 12x - 5

Directions and/or Common Information:

Find the maximum or minimum value for each quadratic equation.

y = 3x2 - 6x + 5
