Give a practical example of the use of inverse functions. While we can compose the functions for each individual input value, it is sometimes helpful to find a single formula that will calculate the result of a composition $f\left(g\left(x\right)\right)$. Function composition is when you apply one function to the results of another function. See Answer. 5. Download free on Google Play. Note: for every example, (to avoid division by zero) Start with the given expression. f(g(x) = f( 3 + 2x) = 2 (3 + 2x) = 6 + 4x. Then my answer is: ( f + g ) (2) = 10, ( h – g ) (2) = –9, ( f × h ) (2) = –12, ( h / g ) (2) = –0.5. We input it into our little function box, and we need to get our output. check_circle Expert Answer. This process puts the g(x) function into the f(x) function everywhere the f(x) function asks for x. An important property of the inverse function is that inverse of the inverse function is the function itself. Added Aug 1, 2010 by ihsankhairir in Mathematics.
