QUADRATIC PARENT GRAPH Q2-U4-L3

We will now investigate the graph of the quadratic function, a function with degree 2. Spend some time graphing the following equations by using a table of values. Connect them into the shape of a parabola.

GRAPHING ABSOLUTE VALUE FUNCTIONS (Day 4)

SWBAT: Graph Absolute Value functions Warm – Up:

In Unit 2, we talked about absolute value in terms of the distance a number is away from zero on a number line. We will now investigate the graph of the absolute value function.

Graph: 𝒚 = |𝒙|

VERTEX The vertex of the absolute value function is the point where the function changes direction. Which coordinates are the turning points (vertex) of the graph above? ( ___, ____ )
