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 decre Given our value of r, we cannot d conclusions for the behavior of y as x increases. Given our value of r, y should tend to increase as x Increases. Given our value of r, y should tend to remain constant as x increases
