      Solving exponential equations like the ones above are easy when each side of the equation have common bases. But problems like 3! x"1 =4 cause problems. With that problem created, we introduced the concept of logarithms. A logarithm is simply an inverse of an exponential. Students typically hear the word logarithm and go into a

      SECTION 3.1 Exponential and Logistic Functions 279 In Table 3.3, as x increases by 1, the function value is multiplied by the base b.This relationship leads to the following recursive formula. In Example 3,g is an exponential growth function, and h is an exponential decay function. As x increases by 1, g x 4 3x grows by a factor of 3, and h x 8 1 4 x decays by a factor of 1 4.
