Step-by-step explanation:

1. height serves as the y-value and shoes as the x-value. because domain is the values of x we take in consideration the units x represents. shoe sizes tend to come in sizes 10, 11,12

2. for this one I relied on process of elimination, 2 & 4 include negative numbers and height, at least here, cannot be negative. (3) is representing the y-value or height. so the only one left is 1

this also makes sense because time is positive and the distance would be too.
