Answer

Brief Explanations:

The age of a baby in days is a continuous variable as it can take on any non - negative real value. The shoe size can be considered a discrete variable in practice (e.g., whole and half sizes). A relation is a function if for each input (age in this case) there is exactly one output (shoe size). Since multiple ages could potentially have the same shoe size, we can't be sure it's a function. The domain (age in days) and range (shoe size) are not restricted to positive integers only (shoe sizes can be non - integer values like 6.5 and age can be any non - negative real number in days).

Answer:

A. The domain of the relation is continuous. B. The domain of the relation is discrete. (False) C. The domain and range are restricted to positive numbers. (False) D. The domain and range are restricted to positive integers. (False) E. The relation is not a function.
