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 .

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
