Answer:
Following are the function description to the given question:
Step-by-step explanation:
In the given-question, three functions are used, that can be defined as follows:
In function 1:
This function is also known as the modulus on the absolute value function, for example:

In the given in the above graph, that is 
In function 2:
In this function, It is an algebraic function that is 
It is also a part of the quadratic polynomial function, and its value is
In function 3:
In this function, it is the cubic polynomial equation that's value is 
In the graph its value is:
A suitable equation will equate the quantity of detergent both before and after the water is added to the solution.
the amount of detergent in 11 gal of 18% solution is the same as the amount of detergent in the 12% solution (after g gallons of water are added)
.18*11 = .12*(11+g)
