The production cost, represented by y, of smart phone devices are equal to the product of computing components (a) and the squar
Marta_Voda [28]

The production cost is an illustration of a quadratic function

<h3>How to determine the equation</h3>

We have the following parameters:

  • Computing components (a)
  • Number of devices (x),
  • Labor (b)
  • Savings on reusable material (c)

Using the instructions in the question, the equation of the production cost would be:

y =ax^2 + bx -c

Hence, the production cost is y =ax^2 + bx -c

<h3>Change the subject of the equation</h3>

In (a), we have:

y =ax^2 + bx -c

Subtract bx - c from both sides

y - bx + c = ax^2

Divide through by x^2

a = \frac{y - bx + c}{x^2}

Hence, the equation that represents the computing component is a = \frac{y - bx + c}{x^2}
