Q. Let f be a continuous function on the closed interval [−2,1], where f(−2)=3 and f(1)=6.Which of the following is guaranteed by the Intermediate Value Theorem?Choose 1 answer:(A) f(c)=4 for at least one c between −2 and 1(B) f(c)=4 for at least one c between 3 and 6(C) f(c)=0 for at least one c between −2 and 1(D) f(c)=0 for at least one c between 3 and 6
The Intermediate Value Theorem: The Intermediate Value Theorem states that if a function f 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 number c in the interval (a,b) such that f(c)=N.
Given Function Values: We are given that f(−2)=3 and f(1)=6. This means that the function f takes on the value 3 at x=−2 and the value 6 at x=1.
Checking Answer Choices: We need to determine if there is a value c in the interval [−2,1] such that f(c) is equal to a certain value. We will check each answer choice to see which one is guaranteed by the Intermediate Value Theorem.
Choice (A) Analysis: For choice (A), we are looking for a value c between −2 and 1 such that f(c)=4. Since 4 is between f(−2)=3 and f(1)=6, the Intermediate Value Theorem guarantees that there is at least one such c in the interval [−2,1].
Choice (B) Analysis: For choice (B), we are looking for a value c between 3 and 6 such that f(c)=4. This choice is not relevant to the Intermediate Value Theorem because it refers to values of f(c), not values of c.
Choice (C) Analysis: For choice (C), we are looking for a value c between −2 and 1 such that f(c)=0. Since 0 is not between f(−2)=3 and f(1)=6, the Intermediate Value Theorem does not guarantee that there is a c such that f(c)=0 in the interval [−2,1].
Choice (D) Analysis: For choice (D), we are looking for a value c between 3 and 6 such that f(c)=0. This choice is also not relevant to the Intermediate Value Theorem because it refers to values of f(c), not values of c.
