The function g is defined below . g(x) = (x - 5)/(x ^ 2 - 36) Find all values of x that are NOT in the domain of g. If there is more than one value, separate them with commas.

Answer :

xKelvin

Answer:

-6, 6

Step-by-step explanation:

So we have the rational function:

[tex]g(x)=\frac{x-5}{x^2-36}[/tex]

The domain of a rational function is all real numbers except for when x is a zero of the denominator.

Thus, to determine the domain restrictions, set the denominator to 0 and solve for x:

[tex]x^2-36=0[/tex]

Add 36 to both sides:

[tex]x^2=36[/tex]

Take the square root of both sides:

[tex]x=\pm 6[/tex]

So, the values that are not in the domain of g is: -6, 6.

And we're done!
