What will the population of the bird species be in 18 years?" The population of an endangered bird species is 200,000. The
population of the bird species decreases at a rate of 9% cach year,

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

graph of this function as shown below:

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
