Plz i really dont have time to do this

#3 represents a linear function; it's obvious that the graph is a straight line.

#4 represents a linear relationship for the same reason.  However, this is NOT a function, because if we choose x=2, there are an infinite number of y values.

Keep in mind that "only one y value for any given x value" is a requirement when you are selecting "functions."

Please try doing one of the other problems on this worksheet yourself.  Then I'd be glad to give you feedback on your work.

A conservative investor invests in more short term bonds than long term bonds because they believe long term bonds are not efficient.

Some investors think that bonds are “safe,” , stocks are “risky”. 

Short-term bonds on the other hand, seems to be attractive to many investors, specifically the conservative ones because they don't require you to tie up your money for long.
