Question

It is required that the production cost must be less than R123 505. Determine the number of devices that will be produced. Show your solution graphically. Use interval notation and indicate the restriction on the number type of you 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
