is the function of f(x)=x^2-4x even, odd, or neither? oh and on what intervals is the function of f(x)=|x+1|+|x-1| increasing?

well the problem does say express the revenue for the bus company as a function of n. maybe this will help: here are the answer choices: 1.(4+0.05n)n 2.(12-0.05n)n 3.12n+4 4.none of these 5.80n 6.8n-4 thanx so much

well i didn't want to post the answers because someone could easily choose an answer choice. i just wanted to compare reiny's answer to the answer i'd already gotten. i wanted to double check from a credible source.
