It however says $\frac{5x}{x+2}$ is rational.

The domain of x is not stated in the book. It just says circle the rational expression below.

comment Find slope of parametric equation
My only other question just to make sure I am doing it correctly as I am fairly new to parametric equations is that I just need to divide and nothing fancy with derivatives right?

@Amzoti Yeah I just rechecked my work and saw I switched it out of the blue for some reason. Thanks for spotting that.

@AndreySokolov As the graph of f(x) will be negative until x=-1. Thanks for spotting that. Which should put my answer at 1.707

@DonAntonio Which yes that is what it seems like on the surface, but when we did these problems in class we never did anything like that. Also if that is the case what is the point of x?
