What is the range of f(x) = 6 − |x + 2|?

Answer and explanation

Correct answer: (−∞, 6]

The governing concept is the range of an absolute-value function. For every real x, |x + 2| is non-negative, so subtracting it from 6 gives f(x) = 6 − |x + 2| ≤ 6. Equality occurs when x + 2 = 0, or x = −2, so the value 6 is attained and must be included. There is no lower bound: as x moves farther from −2, |x + 2| becomes arbitrarily large, making f(x) arbitrarily negative. Hence every real value less than or equal to 6 occurs, and the range is (−∞, 6]. Option B is correct. Option A reverses the bound, option C adds an unjustified lower bound of zero, and option D incorrectly includes values greater than 6.
