    y is delta y= to the derivative of x * delta x?

    I have no idea how to do this question lol, but: lets say you have a change of y along the x component, this is just like saying dy/dx. Now, dy/dx is the change with respect to x of some function y(x), f(x), or g(x), in this case you have the function f(x), where dy/dx of the function f(x)= its derivative which is f'(x), hence: dy/dx= f'(x) and "multiply" both sides by dx you get (delta y) same as dy= f'(x) dx

    that above is all i can say, i think they kinda give you the solution, you just substitue, delta y (dy) by f'(x) dx

    cuz it seems that delta y always equals f '(x)deltax

    it is, they are just trying to visualize it for you using the pytha. theorem.
