Problem:
Let F(x) = (x+2)/(x+7)
so what is F^(-1) (-7)= ?
Hi isnyder,
Not what I got. Check your algebra again and see if you can come up with the correct denominator. Your numerator is fine.
Distribute on the left and group your y terms togther on the left. Continue from there.
See? Now factor out a y on the left and then divide.
