How Do You Evaluate an Exponential Function?

How many people can sit around a table? The 22nd part in a series of 36 continues the work on writing and evaluating expressions to include expressions with two operations. Pupils use models to determine an expression for the number of...

Don't table the resource on writing expressions for relationships in tables. Scholars investigate relationships between variables and write algebraic expressions involving multiplication and division. These expressions help solve...

Let Y represent Yes to using an excellent resource. Pupils first learn to define variables using a complete description in the 19th part in a series of 36. They write expressions involving addition and subtraction in real-world...

Bring your young mathematicians into the fold. Scholars conduct an activity folding paper to see the relationship between the number of folds and the number of resulting layers in the 23rd installment of a 36-part module. The results of...

Evaluating expressions require two things- parentheses and PEMDAS. The video starts with an emphasis on using parentheses to plug in your variables. Once you have everything plugged in, PEMDAS will get your mathematicians to the correct...

Introduce the basics of evaluating a function using function notation with a video that makes connections between evaluating a function and substituting into an expression. The short presentation works through three examples of...

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

Learn the value of evaluating expressions. An educational video shows viewers how to evaluate algebraic expressions for given values of a variable. The video includes a set of five worked examples for the concept.

Demonstrates evaluation (or 'plug-n-chug'), and points out common usage and mistakes.

Discontinuities in the graph? No worries. Pupils investigate the limit of a function given graphically using an interactive. The graph has removable and jump discontinuities.
