Answer:
Hence, the minimum value of the function is 4.
Step-by-step explanation:
We re given the function
Differentiating with respect to x, we get,
Equating f'(x) to 0, we have,
i.e.
i.e.
i.e.
Now, differentiating f'(x) with respect to x gives us,
Thus, the function f(x) have minimum at x= -5 and the minimum value is,
i.e.
i.e.
i.e. f(-5) = 4
Hence, the minimum value of the function is 4.
