To determine if a relation given in a table is a function, check if each input (or x-value) corresponds to exactly one output (or y-value). This means that no x-value should appear more than once in the table with different y-values. If any x-value is paired with multiple y-values, the relation is not a function.

The conversion relation between in and cm are given .By the conversion table the relation we get is as follows. 1 inch =2.54 cm .
The conversion between km and hm is given in metric chart .By conversion table the relation between hm and km is given as . 1 km =10 hm.
To determine if a function represents a proportional relationship, you can use a table of values to check if the ratio of the output (y) to the input (x) remains constant. If the ratios are consistent, the relationship is proportional. Additionally, graphing the function will help you visualize the relationship; if the graph is a straight line that passes through the origin (0,0), then the function is proportional. If either the table or graph does not meet these criteria, the relationship is not proportional.
Given a relational db table that contains data about patients at a doctor's office, and a second table that contains data about prescriptions, do you think that a relationship can be established between the two tables? If so, explain whether the relationship is 1 to 1, 1 to many or many to many.

In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.

In DBMS, a relation instance refers to a particular set of data rows within a database table at a given point in time. It represents the actual values stored in the database for that specific table. Each row in a relation instance corresponds to a record or tuple within the table, containing values for each attribute.
The domain of a function represented by a table consists of all the input values (usually the x-values) listed in the table. These values indicate the specific points at which the function is defined. To determine the domain, simply identify and list the unique x-values from the table. If any values are missing or not represented, they are excluded from the domain.
The ratio of the two variables is not the same for all pairs.
The conversion of km and cm is given .By conversion table ,the relation is given as follows . 1 km=100000 cm . so,12.3 km =1230000 cm .
The conversion between km and hm is given in metric chart .By conversion table the relation between hm and km is given as . 1 km =10 hm.
