What is the value of \(f(x)=\lfloor x+2\rfloor\) at \(x=1.6\)?

Answer and explanation

Correct answer: 3

The governing concept is the greatest-integer, or floor, function. For any real number \(t\), \(\lfloor t\rfloor\) is the greatest integer less than or equal to \(t\). First substitute the given input: \(x+2=1.6+2=3.6\). The greatest integer not exceeding 3.6 is 3, so \(f(1.6)=\lfloor3.6\rfloor=3\). Therefore option A is correct. The answer is not 3.6 because the floor function removes the fractional part by moving downward to the nearest integer. Option B would be obtained by ignoring the added 2, option C by rounding 3.6 upward, and option D by failing to apply the function.
