(1 point) Consider the function f(x) = x2 - 4x + 2 on the interval [0,4]. Verify that this function satisfies the three hypotheses of Rolle's Theorem on the inverval. on f(x) is on [0, 4); f(x) is (0, 4); and f(0) = f(4) = Then by Rolle's theorem, there exists at least one value c such that f'(c) = 0.

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...
