Not sure how to answer these on my homework

DATE PERIOD SCORE (Lessons 1-5 and 1-v/ 1. Use the parent graph f(x) = = to graph the function g(x) =2. 2. Describe how the graphs of f(x) = Ixl and g(x) = - Ixl -2 are related. 3. Given fx) = x2 + 1 and g(x) = Vx -3, find (f+ g)(x) and its domain. 4. MULTIPLE CHOICE Given fx) = 2x - 3 and g(x) = 4x2, what is [f - g] (x)?
