What is f(5) if f(1) = 3.2 and f(x + 1) = (5)/(2) (f(x))

associative property of multiplication

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:

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
