The question first tells me to graph the function to determine any x-intercepts.
y = 20(2/X+1 - 3/x)
When I put it in my calculator, I got x-intercept = (1,0)
Now it tells me to set y = 0 to confirm this result.
0 = 20(2/X+1 - 3/x)
I started working in the brackets:
(2x)/(x)(x + 1) - (3x+1)/(x)(x+1)
(-x+1) / (x)(x+1)
Is this right?
If so, what do I do next? What do I do with the 20?
