Practice 2. Write a formula for the function obtained when the graph is shifted as described. a. f(x) = Vx is shifted up 1 unit and to the left 2 units b. f(x) = |x| is shifted down 3 units and to the right 1 unit. 3. Describe how the graph of the function is a transformation of the graph of the original function f. a. y = f(x - 4) +2 by = f (-x) c. y = 3f (x) d. y =f (x) 4. Given the function f below, draw the transformed function h(x) = -f(x - 2) - 1
