The functions are $\"\"$ , $\"\"$ , and $\"\"$ .

The three functions have even degree.

Draw a coordinate plane.

Graph the functions $\"\"$ , $\"\"$ , and $\"\"$ on same window.

$\"\"$ .

Observe the graph :

Common quality in each graph :

The three graphs passes through the points $\"\"$ , and $\"\"$ .

They have similar end behavior.

The three graphs are symmetric with respect to the $\"\"$ -axis.

Range of the each functions is $\"\"$ .

The difference among the graphs : As the degree increases, the midsection " flattens ".

Common quality in each graph: They have similar end behavior.

They all passes through the points $\"\"$ , and $\"\"$ .

The difference among the graphs : As the degree increases, the midsection " flattens".
