Answer:
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:
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
