Hi,

I hope someone can help.I'm trying to find two points on f(x) = (x+2)/(x-1) where the IROC is -3.I created the difference quotient for the equation and now I just have to solve forxin order to figure out these two points where the IROC is -3.

REALLY what I need guidance on is the meaning behind the the solutions forx. For example, when I plug in 0.001 forhI get two solutions, and when I plug in -0.001 forhI get another two solutions forx. Does this mean I have total of 4 solutions for x on both ends of the instantaneous rate of change of -3? I hope someone can help clarify this confusion for me.

Here the examples I am referring to:

https://www.wolframalpha.com/input/?...x-1)(x-0.001-1))

Also I don't know how to use derivatives yet, so I would appreciate a response which isn't too focused on that.

Sincerely,

Olivia
