Explain why the solution does not include x=-2.

Answer:
see the explanation
Step-by-step explanation:
we have
[tex]\frac{3}{x+2}+4\geq 3[/tex]
Remember that in a quotient the denominator cannot be equal to zero
For x=-2 the denominator in the left side is equal to zero
so
In this problem the value of x cannot be equal to x=-2
Because, For x=-2 the expression in the left side is undefined
