SpletWhen populations grow rapidly, we often say that the growth is “exponential,” meaning that something is growing very rapidly. To a mathematician, however, the term exponential … SpletAn exponential function f with base b is defined by f ( or x) = bx y = bx, where b > 0, b ≠ 1, and x is any real number. Note: Any transformation of y = bx is also an exponential function. Example 1: Determine which functions are exponential functions. For those that are not, explain why they are not exponential functions.
