## Composition and Transformation of Functions

Computing the composition of two functions (Section 1.6) and computing the inverse of a function (Section 1.8), are two of the most important topics we are covering in this module. These algebraic procedures are important in theory and in practice and are relevant in the study of calculus. This discussion activity will help you to become proficient in these skills.

## Discussion on Solving Exponential and Logarithmic Equations

Choose an even numbered problem from page 462 #32-90 in the textbook. Solve the equation and explain how you solved it by stating the rule or property of exponentials, logarithms or algebra that were used in each step. You may neatly hand write the response, make a digital copy and attach it to the discussion if you are having trouble using the equation editor supplied in the tool bar.

## Functions and Their Applications

When you buy your favorite type of chocolate you are charged by how much you want. The cost is therefore a function, because it depends on the number of ounces of chocolate you buy. That is, for each input (weight in ounces), there is one output (cost, say in dollars). By contrast the price of a house is not a function of the lot size on which a house is built because houses on the same size lot may sell for many different prices.
