Example: Evaluating the Function
To evaluate the linear function for specific variables or algebraic expressions, substitute each expression for and simplify:
- Evaluate : Replace with to get . Simplify to yield .
- Evaluate : Replace with the binomial using parentheses to get . Distribute the to obtain . Simplify by combining the constant terms to find .
- Evaluate : This expression requires finding the numerical value of first and adding it to the algebraic expression for . Find . Then, substitute both parts into the sum to get . Simplify by combining the constant terms to find .
