Given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k
2
-2
1/2
-1/2

Step-by-step explanation:

Using the graph we can notice something

let's take the abscissa  -2 and -4

so we can say that :

f(-4)=g(-2)

wait we khow that g(x)=f(k*x)

so x= -2 then let's replace it in the expression : f(k*x)

we get f(-4)=g(-2)=f[k*(-2)]

let's solve the equation: -2k = -4

                                               k = -4/-2

                                                k=2

so finally we get k=2

let's check :

from the graph we get :

we have (-1)*2 = -2

so it is true

answer: 32.68

step-by-step explanation:

x=2

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
