Answer: all
Step-by-step explanation: al, of the answers are literally true
Answer: Last option
Step-by-step explanation:
Note that when the point is not included in the function is marked with an empty circle, and when the point is included in the function is marked with a filled circle.
From the interval
f(x) is represented by the slanted line
that cuts the y-axis at ![y = 4](https://tex.z-dn.net/?f=y%20%3D%204)
The starting point of the line must be filled and the end point must be empty.
Then, from the interval
f(x) is defined by the horizontal line
. The starting point of this line is marked with a filled circle because it includes the point ![x = 3](https://tex.z-dn.net/?f=x%20%3D%203)
Therefore the correct option is option D or the last graph (from left to right)
