how to work symbolic representatios? i need to find the domain and range
Your School Subject is Math, not college.
Since this is not my area of expertise, I searched Google under the key words "'symbolic representations' domain range" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
Working with symbolic representations involves manipulating mathematical expressions and formulas using symbols rather than specific numerical values. To find the domain and range of a function expressed symbolically, follow these steps:
1. Understand the concept: The domain of a function represents all possible input values ("x" values) for which the function is defined. The range, on the other hand, represents all the output values ("y" values) that the function can produce.
2. Identify the function: Determine the mathematical expression or formula that represents the function you are working with. For example, let's say we have the function f(x) = 2x + 1.
3. Find the domain: To identify the domain, consider any restrictions on the input values. Common restrictions include division by zero or taking the square root of a negative number. However, for most basic functions, there are no such restrictions, and the domain is assumed to be all real numbers unless specified otherwise. For our example function, the domain is all real numbers.
4. Determine the range: Finding the range can be more challenging and may require some analysis or manipulation of the function. In some cases, the range can be determined easily based on the behavior of the function. However, for more complex functions, you may need to use calculus or graphing techniques to determine the range. In our example function f(x) = 2x + 1, the range is also all real numbers since the function is a linear function with a constant slope.
Remember, these steps are a general guide, and the process of finding the domain and range can vary depending on the specific function or problem you are working on.
