F(x) = 2x + 4; Find f (x/2)
2x + 10
-8x + 4
12 - 2x
x + 4

me i beg !

step-by-step explanation:

the answer for this question is 38

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:

∠cbe and ∠deb are same-side interior angles.
