To find the derivative of the function f(x) = -(2/3)x using the definition of a derivative, you would apply the limit definition of the derivative, which is:

f'(x) = lim(h->0) [f(x + h) - f(x)] / h

For the given function f(x) = -(2/3)x, you would plug in the function values into this definition and simplify the expression to find f'(x).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
