In Exercises 1-4,
(a) Use the graph to determine any x-intercepts of the graph of the rational function and
(b) Set y = 0 and solve the resulting equation to confirm your result in part (a).
1. y = x + / x - 3

4 -X- 4 6 8 -2 -4

2. y = 2x / x - 3

-2 2 4 6 8 -4

3. y = 3x / x + 1

4 -X- 4 6 8 -2 -4 -2 2 4 6 8

4. y = x / x2 - 4

-4

4 -X- 4 6 8 -2 -4 -2 2 4 6 8 -4
