Observe that in the graph of an exponential function, each y value on the graph occurs only once. Therefore, every y value in the range corresponds to only one x value. So, for any particular value of y, you can use the graph to see which value of x is the input to produce that y value as output.Both exponential growth and decay functions involve repeated multiplication by a constant factor. However, the difference lies in the size of that factor: - In an exponential growth function, the factor is greater than 1, so the output will increase (or "grow") over time. - In an exponential decay function, the factor is between 0 and 1, so the ...An exponential function, where a > 0 and a ≠ 1, is a function of the form. f(x) = ax. Notice that in this function, the variable is the exponent. In our functions so far, the variables were the base. Our definition says a ≠ 1. If we let a = 1, then f(x) = ax becomes f(x) = 1x. Since 1x = 1 for all real numbers, f(x) = 1.The graph is shown in Figure [fig:exp]. Thus, the exponential function is one-to-one over the set of all real numbers and hence has an inverse function, called the natural logarithm function, denoted (as a function of x) as f − 1(x) = lnx. The graph is shown in Figure [fig:ln]. Below is a summary of the relationship between ex and lnx:For any exponential function, f(x) = abx, the domain is the set of all real numbers.
