I have a quadratic graph.
I know that I have the following options:
Vietes formula, vertex (x0,yo), the quadratic equation to get x1,x2. Somehow I don't see how I would get the coefficients A and B. The C coefficient is C=3 as it can be read from the graph easily.
How should I tackle the problem?
Just to note that this graph is the function derivative of a previous graph, in other words
The problems says that I have to find $$f(x)$$ I know that I have to integrate and therefore easily get the equation but I need the coefficients.
