WebThe following sequence of steps help in finding the inverse of a function. Here we consider a function f (x) = ax + b. For the given function f (x) = ax + b, replace f (x) = y, to obtain y = ax + b. Interchange the x with y and the y with x in the function y = ax + b to obtain x = ay + b. Here solve the expression x = ay + b for y. WebThe range tells us that the inverse function has a minimum value of y = -3 y = −3 and a maximum value of y = 0 y = 0. The positive square root case fails this condition since it has a minimum at y = 0 y = 0 and maximum at y = 3 y = 3. The negative case must be the obvious choice, even with further analysis. grandinspired.comWebIntro to inverse functions Quiz 5: 5 questions Practice what you’ve learned, and level up on the above skills Unit test Test your knowledge of all skills in this unit About this unit A function is like a machine that takes an input and gives an output.
