The correct way to write this function is x / (x^2 - 5x - 6). I recommend reviewing the order of operations.
It helps to sketch the graph of f(x) to come up with hypotheses to prove regarding the range.
Hello, atpod1!
As emakarov pointed out, a graph would illustrate the behavior of this function.
I've worked out the domain to be:
but I'm struggling to work out the range.
There are vertical asymptotes at and
Plot a few points and we find that:
. . The graph contains the origin
. . To the far right and far left, the graph approaches the x-axis.
. . To the left of , the graph is below the x-axis.
. . On , the graph is above the x-axis.
. . On , the graph is below the x-axis.
. . To the right of , the graph is above the x-axis.
The graph looks like this:
It appears that will take on all values.Code:| : | : :* | :* : | : : | : * : * | : * : | : * : * | : * : * | : * - - - - - - - + - - * - - + - - - - - - - - - - * -1: | * :6 * : | * : * : | : * : | * : : | : * : | : : | *: : | : *: | : : | :
