Q. Let g g be a continuous function on the closed interval [3,3] [-3,3] , where g(3)=0 g(-3)=0 and g(3)=6 g(3)=6 .\newlineWhich of the following is guaranteed by the Intermediate Value Theorem?\newlineChoose 11 answer:\newline(A) g(c)=2 g(c)=-2 for at least one c c between 3-3 and 33\newline(B) g(c)=2 g(c)=-2 for at least one c c between 00 and 66\newline(C) g(c)=5 g(c)=5 for at least one c c between 3-3 and 33\newline(D) g(c)=5 g(c)=5 for at least one c c between 00 and 66
  1. IVT Explanation: 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 [3,3][-3, 3], g(3)=0g(-3) = 0, and NN00.
  2. Option (A) Analysis: 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)=2g(c) = -2 for at least one cc between 3-3 and 33. Since g(3)=0g(-3) = 0 and the values of gg on the interval [3,3][-3, 3] are between 00 and 66, 2-2 is not between cc00 and cc11. Therefore, the Intermediate Value Theorem does not guarantee that there is a cc such that g(c)=2g(c) = -2.
  3. Option (B) Analysis: (B) g(c)=2g(c) = -2 for at least one cc between 00 and 66. This option is not relevant because the interval for cc should be between 3-3 and 33, not 00 and 66. Additionally, 2-2 is not between cc00 and cc11.
  4. Option (C) Analysis: (C) g(c)=5g(c) = 5 for at least one cc between 3-3 and 33. Since g(3)=0g(-3) = 0 and g(3)=6g(3) = 6, and 55 is between 00 and 66, the Intermediate Value Theorem guarantees that there is at least one cc in the interval cc00 such that g(c)=5g(c) = 5.
  5. Option (D) Analysis: (D) g(c)=5g(c) = 5 for at least one cc between 00 and 66. This option is not relevant because the interval for cc should be between 3-3 and 33, not 00 and 66. However, since 55 is between cc00 and cc11, there is a guarantee that there is a cc such that g(c)=5g(c) = 5, but the interval for cc is incorrect in this option.
