Answer:

6. Draw a vertical line that goes though points (4,7) and (4,9). For a relation to be a function, each input has to have only one output. The input 4 cannot have the output of 7 and 9. This proves that this is not a function

7. The range is 91, 3, 6, 10 and 15)

Explanation:

The range is the answer if you put in the x for range that they give you.

For example:

x ( x+ 1)/2 If I put in 1 for x, I will get

1(1+1)/2

2/2

1

When the input is 1, the output is one. You that for each of the domains given and you will find the ranges (outputs) that I have written above.
