For which pairs of functions is (fºg)(x)= x;
f(x) = x2 and g(x) = 5
o Rx) = { and (x)=
Rx) = *32 and (x) = 2-3x
• Rx)= 3x-2 and g(x) =-3x+2

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
