Rounding calculator to round numbers up or down to any decimal place. Choose ones to round a number to the nearest dollar. Choose hundredths to round an amount to the nearest cent.How do you Round to the Nearest Ten Thousand Rounding off numbers We have …

Quadratic InequalitiesQuadratic inequalities can be solved graphically or algebraically.Solve Graphically: The graph of an inequality is the collection of all solutions of the inequality.Example 1 (one variable inequality): The trick to solving a quadr…

Examples of Applications of Exponential FunctionsWe have seen in past courses that exponential functions are used to represent growth and decay. Let’s look at examples of these exponential functions at work.1. Population: The population of the popular t…

Graphically Represent the Inverse of a FunctionDefinition of an Inverse Relation:If the graph of a function contains a point (a, b), then the graph of the inverse relation of the function contains the point (b, a). To graph the inverse of a function, rev…

Binomial Probability and the Normal CurveQuestion 1: Find the probability of getting exactly 52 heads when flipping a fair coin 100 times. No problem! We can solve this problem rather quickly with the assistance of our handy graphing calculator. Question…

Graphing, Domain and Range of FunctionsThe domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates).Domain and range can be seen clearly from a graph. The two e…

Finding Domains of Composite FunctionsAt times, the domain of a composite function can be a bit confusing. Let’s examine what happens to values as they “travel” through a composition of functions. In this problem, function cannot pick up the value x = 3,…

The Counting PrincipleWhen dealing with the occurrence of more than one event or activity, it is important to be able to quickly determine how many possible outcomes exist. For example, if ice cream sundaes come in 5 flavors with 4 possible toppings, how…

Exponential FunctionsDefinition: The exponential function with base b is defined by f–(x) = bx  where b > 0  , b≠1 Most exponential graphs resemble this same shape. This graph is very, very small on its left side and is extremely close to the x-axis.…
