WebInverse Rational Function. A rational function is a function of form f (x) = P (x)/Q (x) where Q (x) ≠ 0. To find the inverse of a rational function, follow the following steps. An example is also given below which can help you to understand the concept better. Step 1: Replace f (x) = y. Step 2: Interchange x and y.
WebOct 24, 2015 · An exponential function is the inverse of a logarithmic function. Let: log_b(x)=y=> switch x and y: log_b(y)=x=> solve for y: b^[log_b(y)]=b^x y=b^x=> hence: log_b(x) and b^x are the inverse functions. WebIn order to calculate the inverse function log -1 (y) on the calculator, enter the base b (10 is the default value, enter e for e constant), enter the logarithm value y and press the = or …
