Final Answer:
Evaluating f(-4) for the function f(x) = x + 9 yields f(-4) = 5, making option A: f(-4) = 7 incorrect.
Step-by-step explanation:
To find f(-4) for the given function f(x) = x + 9, substitute x = -4 into the function:
f(-4) = (-4) + 9 = 5
Therefore, the correct answer is f(-4) = 5, which doesn't match option A: f(-4) = 7. It's essential to carefully follow the function definition and perform the substitution accurately.
The discrepancy arises from a misunderstanding or misplacement of the constant term in the function. The correct value of f(-4) is 5, not 7. This emphasizes the importance of meticulous computation and adherence to the given function to arrive at the accurate evaluation.
In conclusion, the correct evaluation of f(-4) for f(x) = x + 9 is 5, making option A incorrect. The process involves substituting the given value into the function and performing the arithmetic operations as defined by the function's structure.
