Which function is represented by the ordered pairs in the following function table?

• y=x-3

• y=x+3

• y=3x-5

• y=5x+3

Write the explicit formula for the sequence provided in the table.

Determine whether the sequence appears to be an arithmetic sequence. If so, find the common difference and the next three terms in the sequence.

-6, -12, -18, -24, -30

• Not an arithmetic sequence

• Yes; common difference is 6; next three terms are -35, -41, -47

• Yes; common difference is -6; next three terms are -36, -42, -48

• Yes; common difference is 5, next three terms are -23, -17, -11

Is the relation a function? Why or why not?

• Yes it is a function. Every input has exactly one output

• Yes it is a function. There are more inputs than there are outputs

• No it is not a function. There is an input with two outputs

• Yes it is a function, but I am not sure why

• No it is not a function. There are more inputs than there are outputs
