Step 1
The graphs of the Odd Degree Polynomial Functions will depend mainly on the Leading Coefficient.
If it is Positive the graph will expand feom quadrant 3 to quadrant 1 i.e. like to the graph of $y=x$
On the other hand, If it is Negative the graph will expand from quadrant 2 to quadrant 4 i.e. like to the graph of $y=-x$
Step 2 Step 3 Step 4 The Graphs of the Even Degree Polynomial Functions will depend mainly on the Leading Coefficient.
If it is Positive the graph will expand from quadrant 2 to quadrant 1 i.e. like to the graph of $y={x}^{2}$.
On the other hand, If it is Negative the graph will expand from quadrant 3 to quadrant 4 i.e. like to the graph of $y=-{x}^{2}$
Step 5 Step 6 a) Graph of odd-degree polynomial functions and the lines $y=x\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}y=-x$
b) Graph of even-degree polynomial functions and the lines $y={x}^{2}\phantom{\rule{1em}{0ex}}\text{and}\phantom{\rule{1em}{0ex}}y=-{x}^{2}$
