For which rational expression is -5 an excluded value of x?
spayn [35]

Ration expressions cause excluded values wherever the denominator equals zero.

So, for any expression like

h(x)=\dfrac{f(x)}{g(x)}

-5 is an excluded value if g(-5)=0

For example, the simplest one would be

h(x) = \dfrac{1}{x+5}

In fact, if you try to evaluate this function at -5, you'd have

h(-5)=\dfrac{1}{5+5}=\dfrac{1}{0}

which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.
