Question

Which value of y is NOT part of the range of this function?

f(x) = (9/x – 1) + 6

Answer 1

are there choices?

Answer 2

Nope.

Answer 3

I believe the range is \[(-\inf,6)U(6,\inf)\] due to the fact that if y were to = 6 you would get a false value.

Answer 4

y = 9/(x-1) + 6
so
(y-6)(x-1)=9
x=9/(y-6)1
thus y=6 is not defined

Answer 5

Thank you both

Answer 6

np

Answer 7

bah that should say x=9/(y-6)+1

Answer 8

to find range
find the inverse(assuming there is one)
then find its domain

Answer 9

the domain of the inverse*
