I would say that B) is the correct answer hope this helps!!

solve for "k", to find the "constant of variation",
then plug it back in the y = kx, to get the equation
now
what's is y when x = -1?
well, just plug that in the equation with the found "k" value,
to get "y" :)
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:
