If f'(x) is continuous, f(-5) = 19, and f(-8)= 21 x L -8 f'(x) dx = -2, find f(-8). -5 Recall the second part of the Fundamental Theorem of Calculus. If g is a continuous function on the interval [a, b], then g(x) dx = G(b) - G(a), where G is any antiderivative of g. Note that in this definition, a b. Is there an integral rule that permits the limits of integration to switch places? How can the given expressions be used with the Fundamental Theorem to set up an equation that includes f(-8)?
