The inverse of a function is a generic equation to find the input of the original function when given the output [finding x when given y]. . We know how to graph the inverse of a function, but now we will look into expressing a new inverse function. Like before, let’s keep in mind the “switching x and y” theory. f. -1. (x). The inverse of the function f(x), f. Inverse variation. Recall: variables . x . and . y. show direct variation if . for some nonzero constant . a. .. *Note: the general equation . for inverse variation can be rewritten as . ..  .

When we talk about a direct variation, we are talking about a relationship where as . x increases, . y increases. . or . decreases at a . CONSTANT. 1. Discrete Mathematics: A Concept-based Approach. Introduction. Every relation involves sets and combination of the elements of the sets. One can map the elements of one set to the other. This mapping is also called function. All the functions are relations, but every relation is not a function. In general every program is viewed as a function. Input to the program is a set and output of the program as another set.. Slope of the Tangent Line. If . f. is defined on an open interval containing . c. and the limit exists, then . . and the line through (. c. , . f.

If . f. . is continuous in its domain, then its inverse is continuous on its domain. . If . f. . is increasing on its domain, then its inverse is increasing on its domain . The . inverse . of a relation is the set of ordered pairs obtained by . switching the input with the output. of each ordered pair in the original relation. (The domain of the original is the range of the inverse; and vice versa). The next thing we want to do is talk about some of the properties that are inherent to logarithms. Properties of Logarithms 1. log a (uv) = log a u + log a v 1. ln(uv) = ln u +
