Question

If p left parenthesis y right parenthesis equals startfraction 3 y minus 7 over y minus upper a endfractionp(y)= 3y−7 y−a and p left parenthesis 3 right parenthesisp(3)equals=negative 2−2​, what is the value of upper aa​?

Answer 1

`p(y)=(3y-7)/(y-A)\\\\p(3)=-2=(3(3)-7)/(3-A)=(2)/(3-A)\\\\3-A=(2)/(-2)\\\\3-(-1)=A=4`

The value of A is 4.
