6.
Does the graph represent a function?
If you have an x value that has 2 "y" values it is NOT a function!
If you have an x value that has 2 "y" values it is NOT a function!
a)
Yes, because the vertical line test shows there are no repeating input values
b)
No, because the vertical line test shows there are repeating input values
7.

a)
Graph 1
b)
Graph 2
c)
Graph 3
d)
Graph 4
8.
Is the relation shown a function?
a)
No, because the x-value 11 is paired with 5 and 8.
b)
Yes, because each x-value has only one y-value paired with it.
