Q. Let h be a continuous function on the closed interval [0,4], where h(0)=2 and h(4)=−2.Which of the following is guaranteed by the Intermediate Value Theorem?Choose 1 answer:(A) h(c)=3 for at least one c between 0 and 4(B) h(c)=−1 for at least one c between 0 and 4(C) h(c)=−1 for at least one c between −2 and 2(D) h(c)=3 for at least one c between −2 and 2
Apply Intermediate Value Theorem: The Intermediate Value Theorem states that if a function is continuous on a closed interval [a,b] and N is any number between f(a) and f(b), then there exists at least one c in the interval [a,b] such that f(c)=N. We need to apply this theorem to the function h on the interval [0,4].
Given Function Values: We are given that h(0)=2 and h(4)=−2. This means that the function h takes on at least all values between 2 and −2 on the interval [0,4] because it is continuous.
Option (A) Analysis: Option (A) suggests that h(c)=3 for some c in [0,4]. However, since 3 is not between h(0)=2 and h(4)=−2, the Intermediate Value Theorem does not guarantee that there is a c such that h(c)=3.
Option (B) Analysis: Option (B) suggests that h(c)=−1 for some c in [0,4]. Since −1 is between h(0)=2 and h(4)=−2, the Intermediate Value Theorem guarantees that there is at least one c in [0,4] such that h(c)=−1.
Option (C) Analysis: Option (C) is incorrect because the interval given is [−2,2], which is not the interval over which we know the function h is continuous. The function h is defined on the interval 0,4, so we cannot apply the Intermediate Value Theorem to the interval [−2,2].
Option (D) Analysis: Option (D) is incorrect for the same reason as option (A). The value 3 is not between h(0)=2 and h(4)=−2, so the Intermediate Value Theorem does not guarantee a c such that h(c)=3 in any interval.
