Sagot :

Answer:

The domain of the function f(x) = (x+5)/(x-8) is all real numbers except for x = 8.

This is because the denominator of the function is (x-8), which is equal to 0 when x = 8. Therefore, x = 8 is excluded from the domain of the function. For all other real values of x, the function is defined.

Answer:

x = 8

Step-by-step explanation:

basically we need to find a value of x which makes it not a real number,

if we divide number by 0 , it will not be a real number

so we need to make the demoninator of (x + 5 / x - 8) a 0,
x - 8 = 0
x = 8,
