The maximum and the minimum values, if any of the following functions f(x) = x3 + 1 for all

Expert Answer:

We have

f (x) = x3 + 1,  
Here, we observe that the values of f (x) increase when the values of x are increased and f (x) can be made as large as we please by giving large values of x. So f (x) does not have the maximum value. Similarly, f (x) can be made as small as we please by giving smaller values to x. So f (x) does not have the minimum value also
