What is the range of (f(x)=|x-4|+2)?

Answer and explanation

Correct answer: ([2,\infty))

The absolute value |x-4| measures a distance, so it can never be negative. Its smallest possible value is 0, reached when x=4. Adding 2 to this nonnegative quantity gives f(x)=|x-4|+2, whose least value is 2. Since the absolute value can become arbitrarily large as x moves away from 4, the function has no upper bound.

The value 2 is actually attained at x=4, so the lower endpoint is included. For any number y greater than or equal to 2, choose x=4+(y-2); then |x-4|+2=y. Hence every value from 2 onward occurs, and the range is [2,∞), option A. The values below 2 cannot occur because they would require a negative absolute value.
