Find any points of discontinuity for the rational function.
y= (x+6)(x+2)(x+8)/(x+9)(x+7)

Answer 1

HI!!

Answer 2

set the denominator equal to zero and solve for \(x\)
i.e. solve
\[(x+9)(x+7)=0\] (pretty much in your head)

Answer 3

Could you give me a hint as to what to plug in for x? its early and i cant think right :(

Answer 4

\[x+9=0\]or
\[x+7=0\] is the next step

Answer 5

ohkay i think im over thinking this... would it just x= -9,-7 ?

Answer 6

yup

Answer 7

so what do i do now?

Answer 8

go have a soda, you are done

Answer 9

so x= -9 x=-7are the points of discontinuity?
