Question

Find the nonpermissible replacement for y in the expression y+3/y+3

Answer 1

Answer:

Non-permissible value is $y=-3$

Step-by-step explanation:

we are given equation as

$f=\frac{y+3}{y+3}$

we know that denominator can not be zero

so, we can set denominator =0

and then we can solve for y

$y+3=0$

we can subtract both sides by 3

$y+3-3=0-3$

$y=-3$

So,

Non-permissible value is $y=-3$

Answer 2

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 $(y+3)\neq0$

$y\neq(-3)$

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