Final answer:
To solve the expression 3·f(-4)-3·g(-2), the values of f(-4) and g(-2) are needed, which are not provided. Without these values, an exact answer cannot be computed.
Step-by-step explanation:
The given expression is 3·f(-4)-3·g(-2). To solve this, we need to know the values of f(-4) and g(-2), which aren't provided here. As we are missing these function values, we can't calculate an exact numerical answer. However, we can discuss how to approach this type of problem.
When facing an expression that requires applying functions to given inputs, like f(x) and g(x), we must either have the functions defined or be given their values at the required inputs. Once we have those, we simply apply the arithmetic operations as indicated. For example, if f(-4) were 5 and g(-2) were 1, then our solution would be 3·f(-4)-3·g(-2) = 3·5 - 3·1 = 15 - 3 = 12.
