The volume of a cylinder is 542pi in?. The height of the cylinder is 16 in. What is the radius of the cylinder to the nearest hundredth? The volume of a sphere is 5,055pi m. What is the surface area of the sphere to the nearest square meter?

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:

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
