Find the function f(x) such that f'(r)- 5 sinh(z)- 2 and f(0) = 4. a) O f(x) =-5 cosh(x) - 2r 1 b) O f(x) =-5 cosh(a) + 2 c) O f(r) =5 cosh(r) – 2 z - 6 9. d) O f(x) –5 cosh(r) – 2 1 e) O f(x) =5 cosh(x) – 2 a + 4
Newton’s method for finding a root of f is to calculate x1, x2, ... via the iterative formula xk+1 = xk - f(xk) / f'(xk) starting from x0. For each of the following functions, calculate x1 and x2: (a) f(x) = 10 - x, with x0 =7 (b) f(x) = -x2 + 1, with x0 = 0
a) Let n be a postive integer. In this part a) you will prove the Power Rule for the root functions y 1 Vx = x* on (0, ). Use inverse functions to show that if f(x) x" then the inverse dy function y = f-1(x) = x* has the derivative dx 1r-1. n b) Let n be a postive integer and m be an integer. In this part b) m т you will prove the Power Rule for rational exponents y = xn = on the interval (0, ∞). d Assume the result dx --1 of part a) and use the Chain Rule to show that d m m -1 dx n
