Question

Which statement is true about the local minimum of the

Answer 1

Answer:

D

Step-by-step explanation:

A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.

B is wrong because the function never even reaches 25 on the interval [-2, -2]

C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.

Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.

Hope that helps. :)

Answer 2

Answer: D. Over the interval [4, 7], the local minimum is -7.

Step-by-step explanation: A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.

B is wrong because the function never even reaches 25 on the interval [-2, -2]

C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.

Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.
