Sketch a graph of a function f: [1,2] U [4,6] [0,4] which is not one-to-one (is injective), but is not onto [0,4] (not surjective). 6. 6p. Given relation r, determine the arrow diagram of r, the table form of r, the domain and range of r: 5 r = {(x,y),(y,x), (z, z), (x,z), (y,x), (x,y)} 7. 6p. Find and show on the real line the domain of the following function: f(x) = logs (3-(x + 1)(x + 3)) 1 P
