Question

The maximum & minimum value of y = x + 1/x
in interval [1/3, 4/3]
(1) 2,-2
(2) 10/3,2
(4) None of these​

Answer 1

Answer:

None of these

Step-by-step explanation:

If we treat the equation as a function then,

$f(x) = x + \frac{1}{x}$

This function is defined for all real numbers except when x = 0. The function becomes undefined when x = 0 ( Division by zero is undefined ).

Hence, domain of the function is,

Domain = R - { 0 }

The Range of the function will also be,

Range = R - { 0 }

The minimum and maximum values for this function will belong to the interval of,

$( - \infty , 0 ) ∪ ( 0 , + \infty )$

Where 0 will be excluded.
