The cost of 2 pounds of potatoes is
$3.78. What is the constant of
proportionality that represents the
relationship between the cost, y, to the
number of pounds of potatoes, x?

is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

Step-by-step explanation:

Here we have , The cost of 2 pounds of potatoes is  $3.78. We need to find  the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x . Let's find out:

Cost is y &  number of pounds of potatoes is x  :

, where k is constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

Therefore, is the constant of  proportionality that represents the  relationship between the cost, y, to the  number of pounds of potatoes, x .

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
