4 Logarithmic Functions Every function of the form f (x) = a x passes the Horizontal Line Test and therefore must have an inverse function. This inverse function is called the logarithmic function with base a. 5 Logarithmic Functions The equations y = log a x and x = a y are equivalent.

The MMR vaccine protects against measles, mumps, and rubella (German measles). Many children in the U.S. are immunized as infants and toddlers, but that doesn't guarantee lifetime protection. And not everyone gets vaccinated as a child.Many adults move to the U.S. from countries without immunization programs.he three diseases covered by the MMR vaccine -- measles, mumps, and rubella -- are highly contagious. Viruses cause all three of these illnesses, and they spread through the air.
