For a function to be undefined, the denominator must be zero.
So, to solve the given function, let's equate the denominator to zero.
[tex]x+5=0[/tex]
Then, let's solve for x. Subtract -5 on both sides of the equation.
[tex]\begin{gathered} x+5-5=0-5 \\ x=-5 \end{gathered}[/tex]
Hence, at x = -5, the denominator is zero and it makes the function undefined.
