1. The problem statement: Pretty straight forward: f(x)=1/x Simplify 2f(x)+3 Evidently, the answer is (2+3x)/x but I don't know how to find that, 2. Relevant equations: None, as far as I know 3. The attempt at a solution: 2f(x)+3 = 2(1/x) + 3 = 2/x + 3 I'm of course missing some simple step or identity that could help me, but I can't come up with any thoughts on how to navigate to the correct answer. Any help will be greatly appreciated, thanks!
