How do you simplify and find the excluded values of #2/(y-9)#?

Answer 1

#"excluded value "=9#

#2/(y-9)" is in simplest form"#

The denominator cannot equal zero as this would make the function #color(blue)"undefined"# Equating the denominator to zero and solving gives the value that y cannot be.

#"solve " y-9=0rArry=9larrcolor(red)" excluded value"#

To simplify the expression 2/(y-9), you can start by factoring out the greatest common factor, which is 1. This leaves us with 2/(y-9).

To find the excluded values, we need to identify the values of y that would make the denominator, (y-9), equal to zero. In this case, y-9 = 0 when y = 9. Therefore, the excluded value is y = 9.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
