Page 1 of 19 review of exponential and logarithmic functions an exponential function is a function in the form of f (xb)= x for a fixed base b, where b 0 and b ≠ 1 b is called the base of the exponential function the domain of the function is all real numbers and the range is all positive real numbers. Exponential equations some exponential equations can be solved by using the fact that exponential functions are one-to-one in other words, an exponential function does not take two different values to the same number.

Properties of logarithmic functions exponential functions an exponential function is a function of the form f (x)=bx, where b 0 and x is any real number (note that f (x)=x2 is not an exponential function) logarithmic functions. As with the sine, we don't know anything about derivatives that allows us to compute the derivatives of the exponential and logarithmic functions without going back to basics. Definitions at the most basic level, an exponential function is a function in which the variable appears in the exponent the most basic exponential function is a function of the form [latex]y=b^x[/latex] where [latex]b[/latex] is a positive number.
