End Behavior of Rational Functions

Match each rational function with a description of its end behavior as x gets larger and larger.

• The value of the expression gets closer and closer to 0.

• The value of the expression gets closer and closer to 1.

• The value of the expression gets closer and closer to 9.

• The value of the expression gets closer and closer to 99.

• The value of the expression gets larger and larger in the positive direction (infinity)

Describe the end behavior of the function

•  x →∞, f(x)→⁻∞ and x →⁻∞,f(x)→⁻∞

• x →∞, f(x)→∞ and x→⁻∞, f(x)→∞

• x →∞, f(x)→∞ and x→⁻∞, f(x)→2

The horizontal asymptote equals zero when:

• the degree of the numerator and denominator are equal

• the degree of the numerator is less than the degree of the denominator

• the degree of the numerator is greater than the degree of the denominator

• the numerator equals zero
