Brenton Jackson · Answer 1

42 inches

Step-by-step explanation:

The function states in its second row that for size 2, the range of x (a child's height in inches) is 42 ≤ x < 44. Then, the option 41.9 is incorrect because is less than 42 and x is greater-or-equal-to 42; option 44 inches is incorrect because it is equal to 44 and the equality sign is not included; option 44.1 inches is greater than 44 and x is less than 44; and option 42 inches is correct because x is greater-than-or-equal to 42, that is, the equal sign is included.
