Answer:

Non-permissible value is [tex]y=-3[/tex]

Step-by-step explanation:

we are given equation as

[tex]f=\frac{y+3}{y+3}[/tex]

we know that denominator can not be zero

so, we can set denominator =0

and then we can solve for y

[tex]y+3=0[/tex]

we can subtract both sides by 3

[tex]y+3-3=0-3[/tex]

[tex]y=-3[/tex]

So,

Non-permissible value is [tex]y=-3[/tex]

Answer:

The non permissible value for y is y≠(-3)

Step-by-step explanation:

In this question the given rational expression is (y+3)/(y+3) and we have to get the non permissible values.

Here denominator of the fraction should never be 0 otherwise the given expression will be undefined.

Therefore [tex](y+3)\neq0[/tex]

[tex]y\neq(-3)[/tex]

So the non permissible value is y≠(-3).
