• Relation. It has no repetition of x values.

• Relation. There are common elements in the given set.

• Function. No common x-coordinates exist in the given set.

• Function. It has positive values in some coordinates.

It is an equation containing at least one fraction whose numerator and denominator are polynomials.

• rational function

• rational equation

• rational inequality

• irrational equation

An inequality which involves one or more rational expressions is called

• rational function

• rational equation

• rational inequality

• irrational equation

If the test value makes the inequality ___________________________, then the entire interval is not a solution to the inequality.

• true

• false

• proportional
