Answer:
Step-by-step explanation:
Non permissible replacement for the variables are the values of x which makes the given function undefined .
The given expression is a rational function and the concept is that a zero in the denominator makes the rational expression undefined .
so to know the Non permissible replacement we need to equate the denominator to 0 .
we get
5x + 2 = 0
5x = -2
[tex]x = -\frac{2}{5}[/tex]
It means the Non permissible replacement is [tex]-\frac{2}{5}[/tex]
