Final answer:
The process to find f(4) involves substituting x with 4 in the equation f(x) = 10x - 2x^2, which yields 8, but none of the available options match this result.
Explanation:
The function provided is f(x) = 10x - 2x^2. To find the value of this function at x = 4, we simply substitute 4 for x in the expression. This gives us:
f(4) = 10(4) - 2(4^2).
This simplifies to f(4) = 40 - 2(16) = 40 - 32 = 8. However, this option is not provided in the available choices. There must be a mistake in the options, as the answer should be 8.
