The minimum value this thing can take is 7 because the absolute value of something can't fall below zero. Zero is the minimum of the absolute value function. But, the absolute value function can increase without bound, so you have the situation where 7 is a minimum and infinity is your target.

$[7, \infty)$ Note 7 is included in the range.
