Question

The function f is defined below. X+5x-24 29 Find all values of x that are NOT in the domain off. If there is more than one value, separate them with commas. x = 0 00. 6 ?

Answer 1

$f(x)=\frac{x^{2}+5x-24}{x^{2}-9}$

For the function f(x) to exist,the denominator should not be equal to zero ,i.e $x^{2}-9 \neq 0$

$x^{2} \neq 9$

$x\neq 3,-3$

x=3,-3 are not in the domain of the function f(x) .
