so i have a problem f(x) = -16/(x-7)^2 + 4
so i was asked to find the root.
I know the VA(vertical aymsotopes) is 7, and the denominator is alrdy put into a vertex form V(7,4)
my teacher taught us to pull out the 16, so u get y= -16[1/(x-7)^2 + 4
so when u find the root do, u include the -16 in it too? or do u just work with the bracket and apply the -16 last. can u please tell which way is correct, or show me your way i guess.
