Exponential functions are common in real world applications, such as compound interest and growth and decay problems. As an example, recall the roach reproduction growth model, which was represented as f(x) = 2 x , where x indicated minutes. Exponential Function : an exponential function f with base a and coefficient C is represented by f(x) = Ca x , where a > 0 , a 1 , and C > 0 . Domain of f is ( - , ) and the range of f is ( 0, ) The graph of f is continuous (no breaks). The x-axis is a horizontal asymptote The y-intercept is C and there are no x-intercepts . If
