 First by breaking down the numbers:
 5,670,249,114 = 5,000,000,000 + 600,000,000 + 70,000,000 + 200,000 + 40, 000 + 9,000 + 100 + 10 + 4  which means the Value of 2 is 200, 000<span>2. Second, by using the ones words:
5,670,249,114 = 5 billion + 6 hundred million + 70 ten million + 2 hundred thousand + 4 ten thousand + 9 thousands + 1 hundreds + 1 tens + 4 ones  which means the Value of 2 is 2 hundred thousand

Given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k<br>2<br>-2<br>1/2<br>-1/2
Umnica [9.8K]

Answer:

Step-by-step explanation:

Using the graph we can notice something

let's take the abscissa  -2 and -4

  • the ordinate that goes with -2 using g is 0
  • the ordinate that goes with  -4 using f is 0

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 :

  • f(-2)=2
  • g(-1)=2

we have (-1)*2 = -2

so it is true
