What is the domain of the relation described by the set of ordered pairs {(–2, 8), (–1, 1), (0, 0), (3, 5), (4, –2)}?   {–2, 0, 1, 5, 8} {–2, –1, 0, 4, 5} {–2, –1, 0, 1, 5} {–2, –1, 0, 3, 4}

what is the starting amount? the question is not clear sorry.

step-by-step explanation:

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
