Answer:
B
Explanation:
The dashed lines are problem asymptotes, where the denominator is 0. It's showing those at x = 0 and x = 4. Plug in 0 to answer B and you get
(0)(0-4) and that equals 0
Plugging in 4, you get
(4)(4-4) = 4(0) and that also equals 0
0 is what creates that space in the function and disconnects it
