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.

Measles, mumps, and rubella (MMR) vaccine can protect children (and adults) from all three of these diseases. Thanks to successful vaccination programs these diseases are much less common in the U.S. than they used to be. But if we stopped vaccinating they would return. Who should get MMR vaccine and when? Children should get 2 doses of MMR vaccine: First Dose: 12-15 months of age. Second Dose: 4-6 years of age (may be given earlier, if at least 28 days after the 1st dose)
