Question

For what value of x is the rational expression below undefined? 3x-5/x-6

Answer 1

The answer is 6 as if you plug in 6 in the denominator (6)-6 is 0 which makes the fraction undefined

Answer 2

For x = 6 function would be undefined .

Explanation:

Given :
`(3x -5)/(x -6)`.

To find : what value of x is the rational expression below undefined.

Solution : We have given that
`(3x -5)/(x -6)`.

Undefined function : The value at which denominator of function is zero .

Then ,

We can see denominator is x-6

For x = 6

6- 6 = 0 .

Therefore, For x = 6 function would be undefined .
