If f(x) = x2 - 4x + 8, what is f(3)?

The correct answer is: 5

Since f(x) = x2 - 4x + 8, to find f(3), we simply substitute x with 3 in the function. This gives us f(3) = (3)^2 - 4(3) + 8 = 9 - 12 + 8 = 5. This is why option A is correct. Option B is incorrect because it is the value of x in the function, not the output or f(x). Option C is also incorrect as it does not match the result of our calculation for f(3). Option D is incorrect because it does not match the result of our calculation for f(3). Additionally, it is important to note that the output of a function is not necessarily equal to the input value.
