1. Day 29 Graphing linear functions, inverses of functions and arithmetic sequence

2. Introduction In this presentation, we are interested in summarizing the contents of day 26, 27 and 28 and examine ourselves how best we understood the topics. We are going to discuss the methods of graphing functions, the inverses of functions and the arithmetic sequences.

3. Vocabulary: Graph It is the visual representation of a function Inverse of a function The inverse of a function that maps a collection of numbers in A to another collection of numbers B is a function that maps A and B in opposite direction, that is from B to A. Arithmetic sequence It is a pattern of numbers where the difference between any two consecutive numbers is always equal.

4. Graphing of linear functions Graphing linear functions can be done in a number of ways. • Using coordinates of two points • Using coordinates of two points and a the slope of the line • Using the slope of a line and an intercept • Using the two intercepts of a line Example 1 Find the graph of a linear function whose slope is 2 and y intercept is 1.
