Answer 1

Answer:

The answer is B, It's the only one that doesn't equal to Zero

Step-by-step explanation:

Excluded values are also called points of discontinuity. These are the values that make the denominator equal to zero and are not part of the domain

Basically the answer cannot equal to zero.

2x^2=0

2x^2/2=0/2

x^2=0

x=0

3x+3=0

3x+3-3=0-3

3x=-3

3x/3=-3/3

x=-1

x^2-7=0

x=$\sqrt{7}$, x=$\sqrt{-7}$

-x-5=0

x=$\sqrt{5} i$, x=-$-\sqrt{5} i$
