• falls to the left and rises to the right

• rises to the lefft and falls to the right

• rises to the left and to the right

• idunno

If the degree is ODD and the leading coefficiect is NEGATIVE, then the graph

• falls to the left and rises to the right

• rises to the lefft and falls to the right

• rises to the left and to the right

• idunno

If the degree is EVEN and the leading coefficiect is POSITIVE, then the graph

• falls to the left and rises to the right

• rises to the lefft and falls to the right

• rises to the left and to the right

• idunno

y-intercept: (0,-2)

• the degree is ODD and the leading coefficient is POSITIVE

• the degree is ODD and the leading coefficient is NEGATIVE

• the degree is EVEN and the leading coefficient is POSITIVE
