can you do part 4 & 5 for me 4. How do we define the average value of the function f(x) on the interval [a, b]? (see page 461 of the text) favg 5. Complete the Mean Value Theorem for Integrals on page 462 of the text. If f is continuous on [a, b], then there exists a number c in [a, b] such that f(c)- that is 4. How do we define the average value of the function f(x)...

Prove the following variant of Theorem 4.14. Suppose f : [a, b] - R is 1-1. If f is differentiable at ce [a, b], f'(c) + 0, and f-' is continuous at d = f(c), then f- is differentiable at d and (f=''(d) = Fico
Real analysis subject 6. Prove the following slight generalization of the Mean Value Theorem: if f is continuous and differentiable on (a, b) and limy a f(v) and limyb- f(s) exist, then there is some z in (a, b) such that -a (Your proof might begin: "This is a trivial consequence of the Mean Value Theorem because ...".) .. 6. Prove the following slight generalization of the Mean Value Theorem: if f is continuous and differentiable on (a, b) and...
Find (a) x* and (b) f(x*) described in the "Mean Value Theorem for integrals" for the following function over the indicated interval. f(x) = x2 + x; [ - 12,0).
Logic (a) Let f : [a, b] → R be a continuous function. Prover that there exists ce [a, b] such that con la silany - be a criminatoria per le sue in elan 5(e) = So gladde (b) Define F:R+R by F(x) = [** V1+e=i&t. Prove by citing the appropriate theorem(s) that F is differentiable on R, and calculate F'(c). Be sure to justify your reasoning at every stage.
Theorem 20.8 (The Mean Value Theorem for Integral Calculus). Let f a, bR be continuous, and g a, bR be integrable and nonnegative. Then, there exists acE (a,b) such that (20.3) f(x)g(a)dx - f(c g(x)dr (ii). Apply Theorem 20.8 to show that 1 100 32 Jo (1 +r2)5 Theorem 20.8 (The Mean Value Theorem for Integral Calculus).

R i 11. Prove the statement by justifying the following steps. Theorem: Suppose f: D continuous on a compact set D. Then f is uniformly continuous on D. (a) Suppose that f is not uniformly continuous on D. Then there exists an for every n EN there exists xn and > 0 such that yn in D with la ,-ynl < 1/n and If(xn)-f(yn)12 E.

Under is for reference (Mean Value Theorem): Suppose that f: R6 + R is a function with the following two properties: flo) = 0, and at at any point Te R6 and any increment h, || DFOD | E || ||. Show that f(B1)) (-1,1). Comment. You should use the Mean Value Theorem at some point in this problem. An interpretation with more jargon is that if the operator norm of Df is at most 1 at all points, then...
