Exercise:

1.    

• The degree of the polynomial is 4, which is an even

• The leading coefficient is negative, it is decreasing

• Thus, the end behaviors would be falling to the left and falling to the right

3.  

• The degree of the polynomial is 4 which is an even

• The leading coefficient is positive, it is increasing

• Thus, the end behaviors would be rising to the left and rising to the right

4.  

• The degree of the polynomial is 4, which is an even

• The leading coefficient is negative, it is decreasing

• Thus, the end behaviors would be falling to the left and falling to the right

Use math applications if you don't know how to graph an equation.
