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 1-1 and 33\newline(B) g(c)=0 g(c)=0 for at least one c c between 5-5 and 2-2\newline(C) g(c)=3 g(c)=-3 for at least one c c between 5-5 and 2-2\newline(D) g(c)=0 g(c)=0 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. Option Analysis (A): We need to determine which of the given options 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 1-1 and 33.\newlineSince 3-3 is between g(1)=2g(-1) = -2 and g(3)=5g(3) = -5, the Intermediate Value Theorem guarantees that there is at least one cc in the interval [1,3][-1, 3] such that g(c)=3g(c) = -3.
  3. Option Analysis (B): (B) g(c)=0g(c) = 0 for at least one cc between 5-5 and 2-2. This option is not relevant to the Intermediate Value Theorem because it refers to values between g(1)g(-1) and g(3)g(3), not to values of cc in the interval [1,3][-1, 3].
  4. Option Analysis (C): (C)g(c)=3(C) g(c) = -3 for at least one cc between 5-5 and 2-2. This option is also not relevant to the Intermediate Value Theorem because it refers to values between g(1)g(-1) and g(3)g(3), not to values of cc in the interval [1,3][-1, 3].
  5. Option Analysis (D): (D) g(c)=0g(c) = 0 for at least one cc between 1-1 and 33. Since 00 is not between g(1)=2g(-1) = -2 and g(3)=5g(3) = -5, the Intermediate Value Theorem does not guarantee that there is a cc in the interval [1,3][-1, 3] such that g(c)=0g(c) = 0.
