Exponential Functions 1. What is the definition of an exponential function? Page 412 An exponential function f with base b is defined by f(x) = bx or y = bx, where b is a positive constant other than 1 (b > 0 and b is not equal to 1) and x is any real number. Example: g(x) = 10^x 2. What is the inverse of an exponential function? Page No horizontal line can be drawn that intersects the graph of an exponential function at more

Composition and Inverse Functions provide an opportunity for manipulating expressions using different values. These values can help business owners, data analysts, and even the consumer compare rates and data. Functions also extend independent (x) and dependent (y) variables by graphing in the coordinate plane and creating a visual demonstration of the relationship. The following functions will be used in the required problems. f(x) = 2x+5 g(x) = x2+3 h(x) = (7-x)/3 The first task is to compute

bold black type. Specific direction headings are in yellow, and these are followed by detailed directions in red. Additional comments about the directions appear in blue. Then there are “Try it!” exercises in green. These “Try it!” exercises are a key feature of this tutorial. I have embedded numerous sample Excel spreadsheets so that you can try out the directions right away—without switching into Excel. When you double-click on one of these spreadsheets, you launch Excel, and the spreadsheet “comes

DB2 & SQL Concepts 1.2.1 What is SQL? Structured Query Language (SQL) is a standardized language for defining and manipulating data in a relational database. In accordance with the relational model of data, the database is perceived as a set of tables, relationships are represented by values in tables, and data is retrieved by specifying a result table that can be derived from one or more tables. DB2 transforms the specification

database Primary Key: constraint uniquely identifies each record in a database table. Primary keys must contain unique values. A primary key column cannot contain NULL values. Each table should have a primary key, and each table can have only ONE primary key. SQL: is a standard language for accessing databases. Foreign Key: is a column or combination of columns that is used to establish and enforce a link between the data in two tables. You can create a foreign key by defining a FOREIGN KEY constraint

Common Lab Tasks In each lab, you will follow a series of step-by-step instructions designed to help you explore the environment and gather the information you need to successfully complete the deliverables. In each lab, you will perform identical steps, such as opening the virtual lab, logging in to another server, taking screen captures, and transferring files to your local computer. To avoid repeating steps in the lab itself, those common steps have been collected in this file. You may refer
