Final answer:
The question seems unclear due to a potential typo involving a percentage symbol, but if we interpret the function f(x) to be a standard linear equation, we could infer that h = 12 and k = 6. None of the provided options match these values.
Step-by-step explanation:
The question asks to determine the values of h and k for the function f(x) = x + 12% + 6. This resembles the format of a linear function, which is usually written in the form f(x) = mx + b, where m is the slope and b is the y-intercept. However, the percentage symbol seems to be a typo as it does not fit into this context. Assuming 'h' and 'k' are constants to be added to 'x' in the linear equation, it seems that the correct representation of the function should be f(x) = x + h + k.
If we're considering that h and k are to be added to 'x' individually, then h is likely meant to represent the constant added directly to x, and k the free-standing constant. Since the function is presented as f(x) = x + 12 + 6, it would imply that h = 12 and k = 6. However, none of the answer options exactly match these values, which suggests there may be a misunderstanding in the question or a typo in the options provided.
