Match the volume formula(s) on the right to the appropriate geometric solid on the left. Some solids are associated with more than one formula. Volume Formula

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:

1/4 because there is 4 grades.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
