Add (f + g)(x)= Subtract (f – g)(x)= Multiply = Divide *denominator cannot be =0!!! The domain and range of the new functions could be different than the originals.. Practice Problems. If f(x) = 3x2+7x and g(x) = 2x2-x-1. What are the domain and range for f(x) and g(x) (approximate if necessary)? find (f+g)(x). Find the domain and range. find ... ................
