Answer:
The correct option is D. The interval [2.5, 4] contains a local minimum for the graphed function
Step-by-step explanation:
According to the definition of local mimima, a function has local minima at c if

for all values of x. where, ![x\in [c-\epsilon, c+\epsilon]](https://tex.z-dn.net/?f=x%5Cin%20%5Bc-%5Cepsilon%2C%20c%2B%5Cepsilon%5D)
From the graph it is clear that the given function has local minima at (-0.44,-4.3) and (3,-4).
![-0.44\notin [-4, -2.5], 3\notin [-4, -2.5]](https://tex.z-dn.net/?f=-0.44%5Cnotin%20%5B-4%2C%20-2.5%5D%2C%203%5Cnotin%20%5B-4%2C%20-2.5%5D)
Therefore option A is incorrect.
![-0.44\notin [-2, -1], 3)\notin [-2, -1]](https://tex.z-dn.net/?f=-0.44%5Cnotin%20%5B-2%2C%20-1%5D%2C%203%29%5Cnotin%20%5B-2%2C%20-1%5D)
Therefore option B is incorrect.
![-0.44\notin [1, 2], 3\notin [1, 2]](https://tex.z-dn.net/?f=-0.44%5Cnotin%20%5B1%2C%202%5D%2C%203%5Cnotin%20%5B1%2C%202%5D)
Therefore option C is incorrect.
![-0.44\notin [2.5, 4], 3\in [2.5, 4]](https://tex.z-dn.net/?f=-0.44%5Cnotin%20%5B2.5%2C%204%5D%2C%203%5Cin%20%5B2.5%2C%204%5D)
Therefore option D is correct.
