Final answer:
The function f(x) = -42/4 is a constant, so for f(-2) the value is -10.5, independent of the value of x.
Step-by-step explanation:
The value of the function f(x) when x = -2 for the function f(x) = -42/4 is a straightforward calculation since the function is a constant. This means that the value of f(x) does not depend on x, so f(-2) will be the same as the constant value of the function, which is -10.5. To resolve the function for any value of x, we simply take the constant term which is -42 divided by 4. No matter what x we plug into the equation, the result will be the same since x is not present in the equation.
