Lecture 30 Antiderivatives (Section 4.9) ex. Suppose that the slope of the tangent line of a function f(x)atny x-value is given by 2x − 5. Can we ﬁnd f(x) Def. Af unin F is called an of f on an interval I if for all x in I. ex. Find an antiderivative of the function f(x)= x + x. How many antiderivatives can there be Recall the theorem (page L24 - 8) which states that if two functions have the same derivative on an interval, they can only diﬀer by a constant. Theorem: If F is an antiderivative of f on I,ten is the most general antiderivative of f on hew C represents any constant.
