Calculating a function and drawing a graph in asp.net mvc?

Question

JavaScript

I want to ask how to implement the calculation of a function, for example, y = ax + bx + c on the interval fromX, toX with a step step in asp.net and so that all the data is entered into the database, as I understand it, we must create models with the properties a, b, c, step, fromX, and so on, I want to ask about the logic itself, should it be in the controllers??? Can someone please draw up a plan or something? New to asp.net. And another question, how to draw a graph? I understand using java script
