Quadratic Characteristics examples from a graph

The x-intercepts occur when...

• the function cross the X-axis.

• the function cross the Y-axis.

• at the max or min of the function.

The line of symmetry is...

• the vertical line through the middle of the parabola.

• the Y-axis.

• the X-axis

Domain refers to...

• the X-values allowed or used in the function.

• the Y-values allowed or used in the function.

• How much of the graph you can see

Does this parabola have a max or min at the vertex?

• Max b/c the vertex is the highest point.

• Min b/c the vertex is the lowest point.

What is the domain for any parabola?

• All real numbers

• Between the x-intercepts

• 
  

  Below or above the vertex.
