End Behavior Rational

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 is 99.

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

Describe the end behavior of the graph.

• x →∞, f(x)→⁻∞ and x →⁻∞,f(x)→⁻∞

• x →∞, f(x)→∞ and x→⁻∞, f(x)→∞

• x →∞, f(x)→∞ and x→⁻∞, f(x)→2

• x →∞,f(x)→2 and x→⁻∞, f(x)→∞

Describe the end behavior of the graph f(x) as x approaches negative infinity?
