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

x = -\frac{2}{5}

It means the Non permissible replacement is -\frac{2}{5}
