1) Let R represent the set of all real numbers. Suppose f:R -> R has the rule f(x)=3x+2. Determine whether f is injective, surjective and/or bijective. 2) Let N represent non negative Integers. Suppose f:N -> N has the rule f(n) = 4n + 1. Determine whether f is injective, surjective and/or bijective. I'm confused on how to solve this and could use steps to explain how this would be determined
