Remember the DOMAIN of every quadratic (parabola) is ALL REAL NUMBERS.

There are two options for the range:

above (greater than) a min or below (less than) a max.

In the graph, what is the axis of symmetry?

• The x-axis is the axis of symmetry.

• The y-axis is the axis of symmetry.

• x=1 is the axis of symmetry.

• y=4 is the axis of symmetry.

Know your vocabulary and where to find it on a graph.

X-int, Y-inter, Vertex, Axis of Symmetry

An Axis of Symmetry is a vertical line, thus an X= equation.

The graph of quadratic parent function f was transformed to create the graph of g(x) = f(x + 2) - 5. Which graph best represents g?

• 
• 
• 
• 

The graph of the function f(x) = x² is the parent function.  How is the graph changed when f(x) - 7?

• Shifted up 7 units
• Shifted down 7 units
• Shifted to the right 7 units
• Shifted to the left 7 units

We didn't discuss this much in class, but you will see it again.

Adding/Subtracting OUTSIDE the ( ) will move the parabola UP/DOWN.

Adding/Subtracting INSIDE the ( ) will move the parabola RIGHT/LEFT.

The easiest way to solve a quadratic is to graph.

Make the equation =0, graph, find the x-intercepts.

USE DESMOS!!
