Question

The table represents a sample of ages and people and their shoes size.

Answer 1

Answer:

The table does not represent a function.

Step-by-step explanation:

Every function must have a exactly one y-value for every x-value. Two different x-values can have the same y-value, but two different y-values cannot have the same x-value.

In the table, we see that the same x-value has two different y-values:

$(15, \textbf{10}),\\(15, \textbf{10.5})$

Thus, the table does not represent a function.

Answer 2

73, because when you simply it all adds up and make sense
