Question

how to find the range of
f(x)= (1/(x^2-16))/(1/(x+4))

Answer 1

There are several methods to find the range of the function, the easiest of which is simply graphing it using a graphing calc.

Answer 2

I know but i must also know without graphing it

Answer 3

find the inverse, the domain of the inverse is the range of the function

Answer 4

how would i inverse it?

Answer 5

hmm this one will get a little tricky because of the x^2, are you sure you are saposed to do this one without a graph?

Answer 6

is it simply x+4 / x^2 - 16 ?

Answer 7

ya, i was supposed to do it without graphing but i didn't really get how to do it

Answer 8

isn't the range all real numbers except 0
