Question 286540: Hello! Please help me solve this composite function. What is g(f(x))where f(x)= 1/SQURT x-3 and g(x)= 2/x+1? I am able to plug in f(x) into g to get 2/(1/SQURT x-3)+1 but then get stuck with the algebra. How do I simplify this? I turned (1) into root of (x-3)/root of (x-3) to establish a common denominator but am not seeing how to get the answer which my book says is 2/(root of x-3)+1. Thank you in advance for your help :)
