What is (g(-2.2)) for the ceiling function (g(x)=\lceil x \rceil)?

Answer and explanation

Correct answer: (-2)

The direct answer is option A:
\(g(-2.2)=-2\). The ceiling function gives the smallest integer that is greater than or equal to the given number. On the number line, \(-3<-2.2<-2\). Therefore, \(-2\) is the first integer at or above \(-2.2\), even though it is numerically less negative. Option A is correct because \(-2\ge -2.2\). Option B, \(-3\), is smaller than \(-2.2\), so it cannot be the ceiling. Option C, \(2\), changes the sign and is not the nearest required integer. Option D, \(3\), is also positive and too large. Do not confuse ceiling with rounding: \(-2.2\) rounds to \(-2\), but the ceiling rule is based on the least integer not below the number. Memory cue: ceiling means move upward on the number line, including for negative numbers.
