$-3 \cdot f(-8)+7 \cdot g(2) = \square$

The expression − 3 c d o t f ( − 8 ) + 7 c d o t g ( 2 ) cannot be evaluated without knowing the values of f ( − 8 ) and g ( 2 ) . Since these values are not provided, the expression remains unevaluated.
Explanation

Problem Analysis We are given the expression − 3 c d o t f ( − 8 ) + 7 c d o t g ( 2 ) and we need to evaluate it. However, we are not given the definitions of the functions f ( x ) and g ( x ) , nor are we given the values of f ( − 8 ) and g ( 2 ) . Without this information, we cannot evaluate the expression.

Examples
This problem demonstrates the importance of having complete information before attempting to solve a mathematical expression. In real life, this could be analogous to needing all the necessary data before making a financial forecast or having all the ingredients before starting a recipe. Without all the required inputs, the result cannot be accurately determined.

To evaluate − 3 ⋅ f ( − 8 ) + 7 ⋅ g ( 2 ) , we need the values of f ( − 8 ) and g ( 2 ) , which are not provided. Without these function values, the expression cannot be calculated. Therefore, the evaluation remains incomplete.
