Question

Which of the following is the simplified form of y^2+y-12 divided by y^2-9 with restriction:
i know it is y+4/y+3 what is the restriction?

Answer 1

restrictions make the denominator be zero

Answer 2

i dont get it.....

Answer 3

\[\frac{y^2+y-12}{y^2-9}\]the denominator cannot be zero, so the function is undefined when\[y^2-9=0\to y=\pm3\]
