Find the maximum or minimum value, if any, without using derivatives, – InterviewSolution

1.

Find the maximum or minimum value, if any, without using derivatives, of the function:(5x – 1)2 + 4

Answer»

It is given that f (x) = (5x – 1)² + 4 with minimum value 4 where 5x – 1 = 0

Here the maximum value cannot be found i.e. when x increases even f (x) increases

Therefore, f (x) does not have a maximum value.
