Answer 3

A requirement for a relation to be a function is that a certain input has to give always the same output. So, put the values you want for input and output and save one row for the pair 1, -3. Now you have that for input=1 you may have two possible outputs: +3 and -3. This is enough to say it is not a function

Answer 4

s what do i do now

Answer 5

fill two rows with whatever the pairs you want

Answer 6

2,5,6

Answer 7

You already have row1: 1,+3
write:
row2: Input=2, output=5
row3: input=4, output=6
row4: input=1, output=-3

Answer 8

yoe see we have forced two different outputs for the same input. For input=1 we have output=+3 (given by the problem) and output=-3
This is enough to say it is not a function. Remember "IT IS A FUNCTION IF SAME INPUT GIVES SAME OUTPUT"

Answer 9

got it now?
