Question

What is the excluded value for `y=(x+2)/(x-1)`?

Answer 1

1

Explanation:

To make the denominator 0, you need to do the following, `0=x-1` --> `0+1=x-1+1`---> `1 =x`

Answer 2

`x=1`

Explanation:

The denominator of y cannot be zero as this would make y undefined. Equating the denominator to zero and solving gives the value that x cannot be.
