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