Introduction Curve Discussion 1st Derivative

The illustration shows the function f(x)= x^3+ 2x^2 and its derivative f'(x)= 3x^2 +4x. The graph is available as a threshold copy for blind students (8 point Braille) and as a graph for visually impaired students. In each case 3 different versions exist: Function 1st derivativ Function and 1st derivative Hint: It makes sense to mark the vertex points on the swell copy with a pin.
