You can put this solution on YOUR website! x/(x+9)>0
First we have to find the inflection points in this expression.
There is a vertical asymptote at x=-9 because division by zero is not allowed.
There is a horizontal asymptote at y=1 because x is 1st degree on the top and bottom.
.
Testing around the vertical asymptote and zero:
When is less than -9, y is always positive because the numerator and denominator are always both negative.
When x is more than -9 and less than zero then the expression is negative.
When x is greater than zero the expression is always positive.
.
X(-infinity, -9)U(0,infinity) The solution set.
