Label as a function or not..
never [62]

Answer:

5.  not a function

6.  function

7.  not a function

8  function

9.  not a function

10  function

Step-by-step explanation:

5.  this fails the vertical line test.  Since a vertical line would touch more than one point this is not a function

6.  this is a function.  Each input (or x)  has only one output, so it is a function

7.  This is not a function .  X=2  goes to more than one y value x =2 goes to y=5 and y=6.  so it is a relation  not a function

8.  this passes the vertical line test.  Since a vertical line  does not touch more than one point this is  a function

9.  This is not a function .  X=5  goes to more than one y value x =5 goes to y=-4 and y=1.  so it is a relation  not a function

10. this is a function.  Each input (or x)  has only one output, so it is a function
