The derivative of a function f(x) is defined by f' (x) = lim h-0 Now consider the function f(x) = By definition of the derivative, we have: x2 + 17 f' (x) = lim h -0 This limit is of type: (No answer given) We perform algebraic manipulations to evaluate the limit, and obtain that the derivative f' (x) is: f' (x ) = Check
