Question

f(x) = x³ \[-\] 1 on R .

Answer 1

We can observe that f(x) increases when the values of x increase and f(x) decreases when the values of x decrease.

Also, f(x) can be reduced by giving smaller values of x.

Similarly, f(x) can be enlarged by giving larger values of x.

So, f(x) does not have a minimum or maximum value.
