Explanation:

Step1: Substitute x = 6 into function

$f(6)=\sqrt{2\times6 - 17}$

Step2: Calculate the value inside the square - root

$2\times6-17=12 - 17=-5$

Step3: Determine if the result is a real number

Since the square - root of a negative number is not a real number in the set of real numbers, the function value is undefined.
