If f(x) = sqrt(x^2-1) and g(x) = sqrt(x-1), which expression represents f(x)/g(x) for x>1? Can you do the above problem and provide the answer? 3/27/2014 | Crystal from Philadelphia, PA | 1 Answer | 0 Votes Mark favorite Subscribe Comment
If f(x) = √(x^2-1) and g(x) = √(x-1), then, for x>1, f(x)/g(x) = √(x^2-1)/√(x-1) = √((x^2-1)/(x-1)) = √((x+1)(x-1)/(x-1)) = √(x+1), x>1. 3/27/2014 | Steve S. Comment
