Question

Finding an Inverse “In Your Head” In this margin notes in this section we pointed out that the inverse of a function can be found by simply reversing the operations that make up the function. For instance, in Examplewe saw that the inverse of

is

Because the “reverse” of “Multiply by and subtract ” is “Add and divided by ”. Use the same procedure to find the inverse of following functions. Now consider function another function:

Is it possible to use the same sort of simple inversal of operations to find the inverseof this function? If so, do it. if not, explain what is different about this function that makes this task difficult.
