Function or no function 12 question please help

1. not a function.

2. is a function.

3. is a function.

4. not a function.

5. is a function.

6. not a function.

7. not a function.

8. is a function.

9. not a function.

10. is a function.

11. not a function.

12. not a function.

Step-by-step explanation:

1. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

2. is a function because each input only goes to one output.

3.  is a function because each input only goes to one output.

4. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It does not pass the vertical line test.

5. is a function because each input only goes to one output.

6. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

7. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs.

8. is a function because each input only goes to one output. It also passes the vertical line test.

9. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

10. is a function because each input only goes to one output. It also passes the vertical line test.

11. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

12. not a function because the same input goes to 2 different outputs. A function input cannot have 2 outputs. It also did not pass the vertical line test.

Hope this helps!

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
