Question

Hence, write down the equation with y as the subject (in terms of x). The value of m and q must be indicated.


Discuss whether it is possible that any devices are produced if the production cost is R 0,00

It is required that the production cost must be less than R 123 505. Determine the possible number of devices that will be produced. Show your solution graphically. Use interval notation and indicate the restriction on the number type of your answer. Interpret your answer.​

Answer 1

The production cost is an illustration of a quadratic function

The equation of the production cost is $y = ax^2 + bx - c$

How to determine the equation

From the complete question, we have the following parameters:

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

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

$y = ax^2 + bx -c$

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

When the production cost is less than 123,505;

The equation becomes

$ax^2 + bx - c < 123,505$
