*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (g\circ f)(x)\ =\ g\left(f(x)\right)]


Since *[tex \LARGE \text{dom}(g)\ =\ \left{x\ \in\ \mathbb{R}\ |\ x\ \not =\ -3\right\}], *[tex \LARGE f(x)] cannot be -3 or undefined.  Hence, *[tex \LARGE x] cannot be equal to 7 because *[tex \LARGE \text{dom}(f)\ =\ \left{x\ \in\ \mathbb{R}\ |\ x\ \not =\ 7\right\}] nor can it be a value that makes *[tex \LARGE f(x)\ =\ -3] .
