A function f : Z → Z is defined by f(n) = 2n + 2. Determine f(E), where E is the set of even integers. Determine f-1(D), where D = {6k : k E Z}. (a) (b),

Find the domain of the function: f(x) O All Real Numbers O {x\ x=4} Ο Ο Ο O {x|x = 4, x= 3} O (X1X=3) 3} x2 - 5x+6 x² - 7x+12

Let f (x): x=3 = O x=-3 O y=5 O y=-5 O y=0 2(x+3)² - 5. What is the axis of symmetry of the graph of f?
