You mean f(x)= x/(x+ 2), right? What you wrote is f(x)= 1+ 2= 3!

Whata) show that f'(x) > 0 for all x in the domainisthe derivative? Do you know the "quotient rule"?

Dividing both numerator and denominator of givesb) State the equation of the horizontal asymptote of y = f(x)

What happens as x "goes to infinity"?

Thanks
