Get started for freeSuppose \(f\) is an odd function and is differentiable everywhere. Prove that for every positive number b, there exists a number c in \(( - b\;,\;b)\) such that \({f^\prime }(c) = \frac{{f(b)}}{b}\).
Suppose f is a continuous function defined on a closed interval (a,b).
(a) What theorem guarantees the existence of an absolute maximum value and an absolute minimum value for \(f\)?
(b) What steps would you take to find those maximum and the minimum values?
If \({f^\prime }(x) = c\) (c a constant) for all x, use Corollary 7 to show that \(f(x) = cx + d\) for some constant d.
9โ12 โ Verify that the function satisfies the hypotheses of the Mean Value Theorem on the given interval. Then find all numbers that satisfy the conclusion of the Mean Value Theorem.
11. \(f(x) = \ln x\), \((1\,,\;4)\)
A Norman window has a shape of a rectangle surmounted by a semicircle. (Thus the diameter of the semicircle is equal to the width of the rectangle.) If the perimeter of the window is 30 ft, find the dimensions of the window so that the greatest possible amount of light is admitted.
