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.

Immunization : Measles, Mumps and Rubella MMR Vaccine. Vaccines (or needles or baby shots) are the best way to protect against some very serious infections. The Canadian Paediatric Society and the National Advisory Committee on Immunization strongly recommend routine immunization. The MMR vaccine is a three-in-one needle that protects against measles, mumps and rubella (German measles). It should be given to children soon after their first birthday. A second dose is given in combination with varicella (chicken pox), as MMRV (a four-in-one needle) at 4-6 years of age.
