New operator definitions 2

The  exercise appears under the Algebra I Math Mission. This exercise defines non-standard symbols as operators to create functions.

Types of Problems
There is one type of problem in this exercise:


 * 1) Find the value of the functions: This problem provides a function using a atypical symbol as an operator. The student is expected to obey the function defined and find the output based on the inputs provided.Nod2-1.png

Strategies
Knowledge of function mechanics, such as the relationship between input and output, is encouraged to ensure accuracy and efficiency on this exercise.
 * 1) Some of the operators that are used often are #, *, and @.
 * 2) Just as with an x or a y, replace the value of the variable with the number specified and obey the rule.
 * 3) These problems will have multiple operators used to arrive at the answer via composition and possibly other intermediate operations.

Real-life Applications

 * 1) Functions are the building blocks of all modeling, and so they are vital to represent approximations of real-life situations in almost all fields of inquiry.
 * 2) New operator definitions show up often on SATs and other standardized exams.
