Computer. (Round your answer to four decimal places.) As x increases, does the value of r imply that y should tend to increase or decrease? Explain. Given our value of r, y should tend to decrease as x increases. Given our value of r, y should tend to increase as x increases. Given our value of r, we cannot draw any conclusions for the behavior of y as x increases. Given our value of r, y should tend to remain constant as x increases
