Question

It's been a while since I've taken a math class and I'm stressed please help me out. The question is circled.

Answer 1

where it is not defined is where the denomenator is equal to 0 because division by 0 is not allowed

2x=denomenator
find the value of x wher
2x=0
x=0


the restricted value is 0

Answer 2

-3/2x

The rational expression would not be defined only when the denominator is divided by 0

That is:

2x =0

x = 0/2

x =0

Hence it would not be defined when x = 0.

Hope this helps.
