Need to create a function in Precalc.... 1. The problem statement, all variables and given/known data Let a be the # corresponding to the first letter of your name in the alphabet. Let b be the # corresponding to the first letter of your last name. Come up with a function f such that f(a)=b and f(b)=a (you need to write the answer as y=f(x)). 2. Relevant equations My #'s would be f(19)=10 and f(10)=19 3. The attempt at a solution I would just like some help starting off....I feel a bit lost. Thanks for your time!
