If i use the formula for tangent line approximation F(x)=f(a)+f'(a)(x-a) and i use the function x^2 i end up with F(x)=x^2+2x(x-a) what would i use for my (x-a)

    the smaller your a, the better your approximation

    usually, with problems like that, our teacher would ask the error, based on the a used for a given interval

    Well the goal is to come up with three problems to give to the teacher (don't ask me why) but this is the first time i have ever seen this stuff.

    Ok, so linear approximation, is F(x0) + F'(x0)(x-x0), (x-x0) is deltax, or change in x. the smaller the change, the better the accuracy (usually)

    maybe you can choose functions whose accuracy changes drastically depending on what delta you choose

    it's not really about the a or x0 that you use, but that delta x
