solve for both please and thank you

The piece of x) given by y = 2:1? 4 has the restricted domain 3: 2 1. Plugging the value 3: = 1 into 3; : 2m 4 gives us 3; : 2(1) 4 : 2. Since the inequality :1: Z 1 allews fer equality, we must place a closed circle at the point (1, 2) and keep the part ef the graph to the right of :I.' = 1, as shown here
