- 1)/(x
2
- 4x + 3) has a hole and a vertical asymptote. Which window best supports seeing both x-locations?
A
Window [-5, 0] by [-10, 10]; it misses both special x-values
B
Window [0, 5] by [-10, 10]; it includes the hole at x = 1 and the vertical asymptote at x = 3
C
Window [0, 2] by [-10, 10]; it shows the hole but misses the asymptote
D
Window [2, 5] by [0, 10]; it shows the asymptote but misses the hole and negative values
