Question

Am I correct? Restrictions on variables? What restrictions do these variables have? x - 4 / x - 3 My answer: x cannot be +- 3, or +-4. Am I correct? Thank you!

Answer 1

x cannot be 3

Answer 2

Why is that?

Answer 3

Why not 4 as well?

Answer 4

For the denominator (x-3) is cannot equal 0

x-3=0 --> So x cannot be 3 as we get an undefined value since we cannot divide by 0.

However as long as the denominator is not 0, it numerator can be any value even 0 since 0/a=0 where a is some value :)
