Thread: Transformation of functions?

I'm doing some seemingly basic transformations with functions and I need a quick little help.

The universal mapping notation for solving the equations is: (x/k +d, ay +c)

Now, if I'm correct, the d is always opposite right? If you have a minus for the equation, it is + when you input and vice versa. But what about the c? It says +c. Does that mean it is always +? Or is it whatever it is in the equation?

Thank you!

The term "universal mapping notation" is not universally accepted in mathematics. This seems to be some approach to solve equations that is described in a particular textbook. It would help if you describe the situation and the terms that you are using, such as "when you input."
