College Algebra: Lesson 7.3 Logarthmic Functions and Their Graphs. Every exponential function of the form , is . one-to-one. and thus must have an inverse. This means that we must define a new function, the . inverse. of he exponential function is the . LOGARITHMIC FUNCTION, defined as follows. For x > 0, a > 0, and , if and only if . ................
