Q. Let g g be a continuous function on the closed interval [1,3] [-1,3] , where g(1)=2 g(-1)=-2 and g(3)=5 g(3)=-5 .\newlineWhich of the following is guaranteed by the Intermediate Value Theorem?\newlineChoose 11 answer:\newline(A) g(c)=3 g(c)=-3 for at least one c c between 5-5 and 2-2\newline(B) g(c)=0 g(c)=0 for at least one c c between 5-5 and 2-2\newline(C) g(c)=0 g(c)=0 for at least one c c between 1-1 and 33\newline(D) g(c)=3 g(c)=-3 for at least one c c between 1-1 and 33
  1. Intermediate Value Theorem: The Intermediate Value Theorem states that if a function is continuous on a closed interval [a,b][a, b] and NN is any number between f(a)f(a) and f(b)f(b), then there exists at least one cc in the interval [a,b][a, b] such that f(c)=Nf(c) = N. We are given that gg is continuous on the interval [1,3][-1, 3], g(1)=2g(-1) = -2, and NN00.
  2. Analysis of Options: We need to determine which statement is guaranteed by the Intermediate Value Theorem. Let's analyze each option:\newline(A) g(c)=3g(c) = -3 for at least one cc between 5-5 and 2-2: This statement is incorrect because 5-5 and 2-2 are values of gg, not values of cc.
  3. Correct Statement: (B) g(c)=0g(c) = 0 for at least one cc between 5-5 and 2-2: This statement is incorrect because it refers to values of cc between 5-5 and 2-2, which are not in the domain of the function gg, but rather in its range.
  4. Application of Theorem: (C) g(c)=0g(c) = 0 for at least one cc between 1-1 and 33: This statement is a possible application of the Intermediate Value Theorem since 00 is between the values of g(1)=2g(-1) = -2 and g(3)=5g(3) = -5, and the interval [1,3][-1, 3] is the domain over which gg is continuous.
  5. Application of Theorem: (C) g(c)=0g(c) = 0 for at least one cc between 1-1 and 33: This statement is a possible application of the Intermediate Value Theorem since 00 is between the values of g(1)=2g(-1) = -2 and g(3)=5g(3) = -5, and the interval [1,3][-1, 3] is the domain over which gg is continuous.(D) g(c)=3g(c) = -3 for at least one cc between 1-1 and 33: This statement is correct because cc33 is a value between g(1)=2g(-1) = -2 and g(3)=5g(3) = -5, and according to the Intermediate Value Theorem, since gg is continuous on [1,3][-1, 3], there must be at least one cc in the interval [1,3][-1, 3] such that g(c)=3g(c) = -3.
