Define the function formula for each of the following given the function definitions for f f, g g, and h h. f ( x ) = √ x + 5 f(x)=x+5 g ( x ) = 3 x − 5 g(x)=3x-5 h ( x ) = 5x(x)=5x f(g(x))= Previewg(f(x))= Previewh(f(x))= Preview

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
