Consider the following statements in respect of the function f(x)=x+ 1 x : 1. The local maximum value of f(x) is less than its local minimum value. 2. The local maximum value of f(x) occurs at x=1 . Which of the above statements is/are correct?
Options
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Correct answer
A. 1 only
Step-by-step solution
We have x+ 1 x -2 or x+ 1 x 2 Hence Local minimum value of f(x) is 2 and Local maximum value g(x) is -2 Hence statement 1 is correct.
