If f(x)=x-2 and g(x)=1/2x, find g(f(x))

1/2x -1

Step-by-step explanation:

g(f(x) means put f(x) in for x in the function g(x)

g(f(x)) =

g(x) = 1/2 x

g(f(x) = 1/2 (f(x))

        =1/2 ((x-2))

        =1/2 x -1/2(2)

         =1/2 x-1

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
