Final answer:
The expression f(-4) - 3.g(-2) cannot be evaluated without knowing the specific values of the functions f and g at the given points. Therefore, the correct answer is 'Not enough information provided.'
Step-by-step explanation:
The question asks to evaluate the expression f(-4) - 3.g(-2). This is a straightforward substitution problem in mathematics, where 'f' and 'g' represent two different functions. To solve for the expression, you would need to know the specific values of f(-4) and g(-2). Without these values, it is impossible to determine an exact numerical answer. Therefore, the correct answer is A. Not enough information was provided.
When encountering subtraction in mathematics, as shown in example 5 - (+3) = 2, the sign of the number being subtracted changes before the operation is carried out. Similarly, if you subtract -6 from 2, the equation becomes 2 - (-6) = 2 + 6 = 8. This principle is important for understanding how subtraction operates within various mathematical expressions.
