Question 4 (1 point) if f(x) is a one-to-one differentiable function with f(a) f'(a) +0, then...
Question 6 (1 point) Suppose a function f(x) is differentiable everywhere and has a local minimum at x=c. If f(x)<O when x<c, and f'(x)>0 when x>c, then by the Global Interval Method we know x=c is O a local maximum an absolute maximum a local minimum an absolute minimum
TRUE OR FALSE PRINGLE???? The point (-1,-1) is a saddle point for the function f(x, y) = x2 - y2 + 2(x - y). O True False Question 14 1 pts TRUE/FALSE: In order to optimize a differentiable function f(x, y)over the disk (filled in circle) x2 + y2 < 4, you first find all critical points in that disk, and then sort them by output. Then, you use the method of Lagrange Multipliers (perhaps) to optimize the function on...
4. (a) Assume a function h is differentiable at some point to. Is it true that h is continuous on some open-neighbourhood of xo? Provide either a proof or a counterexample. (b) Let f be twice differentiable on R and assume that f" is continuous. Show that for all x ER S(x) = S(0) + s°C)x + [ (x - 1))"(dt. (C) Deduce that for any twice continuously differentiable function f on R and any positive x > 0, x...
Question 7 14 Let f be a twice differentiable function, and let f(6) = 7, f'(6)=0, and f" (6) = 0. Which statement must be true about the graph of f? (6,7) is a local minimum point (6,7) is a local maximum point (6,7) is a global maximum point There's not enough information to tell. (6,7) is a point of inflection (6,7) is a global minimum point Question 5 14.3 pts Let f be a twice differentiable function. y С...
differentiable function and there exists 0 <A < 1 (6) Suppose that f : R" -> R" is a such that |f'(x)|< A, for all x E R". Prove that the function F(x)= x - f(x) maps R" one-to-one and onto R". (Suggestion: Use the Contraction Mapping Principle Why not use the Inverse Function Theorem?) differentiable function and there exists 0
4. Let F be a continuously differentiable function, and let s be a fixed point of F (a) Prove if F,(s)| < 1, then there exists α > 0 such that fixed point iterations will o E [s - a, s+a]. converge tO s whenever x (b) Prove if IF'(s)| > 1, then given fixed point iterations xn satisfying rnメs for all n, xn will not converge to s.
Question 14 1 pts TRUE/FALSE: In order to optimize a differentiable function f(x, y)over the disk (filled in circle) x2 + y2 < 4, you first find all critical points in that disk, and then sort them by output. Then, you use the method of Lagrange Multipliers (perhaps) to optimize the function on the boundary circle. Finally, you compare all special points and circle the biggest/smallest outputs and type them into webassign. True O False
True or False If f is differentiable everywhere and f^′(x)<0 for all x, then lim x→∞ f(x)= −∞
