Elijah keeps track of when his baby sister’s shoe size increases. He notes that on a certain day her shoe size increases to 6½. Select all the true statements about the relation Elijah observes between his sister’s age, in days, and her shoe size. The domain and range are restricted to positive integers.
The domain of the relation is discrete.
The domain and range are restricted to positive numbers.
The domain of the relation is continuous.
The relation is not a function.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
