A reversible heat pump is a climate-control system that is an air conditioner and a heater in a single device. Operated in one direction, it pumps heat out of a house to provide cooling. Operating in reverse, it pumps heat into the building from the outside, even in cool weather, to provide heating. As a heater, a heat pump is several times more efficient than conventional electrical resistance heating. In this section, we will consider the reverse nature of functions. Suppose a fashion designer traveling to Milan for a fashion show wants to know what the temperature will be. He is not familiar with the Celsius scale. ## Classzone.com has been retired

In mathematics , an inverse function or anti-function  is a function that "reverses" another function: if the function f applied to an input x gives a result of y , then applying its inverse function g to y gives the result x , i. Thinking of this as a step-by-step procedure namely, take a number x , multiply it by 5, then subtract 7 from the result , to reverse this and get x back from some output value, say y , we would undo each step in reverse order. In this case, it means to add 7 to y , and then divide the result by 5. In functional notation , this inverse function would be given by,. Not all functions have inverse functions. Let f be a function whose domain is the set X , and whose codomain is the set Y. Practice - Inverse Functions.
