#1: f(x) = x^2-4x find vrtex, axis ofsym, y-int, x-int if any, domain, range, where increasing and decreasing. I got.... vertex: 2,4 axis of sym: x=2 D= (-infinity, infnity) range= [4,infinity) im stuck of the intercepts because when i plug i 0 for x i get yint of 0 but the gr...

Check my precalc?
