\left(\frac{\sqrt{x}+1}{\sqrt{x}-1} -\frac{x-2\sqrt{x}-3}{x-1}\right)\d iv \left(\frac{x+3}{x-1}+\frac{2}{\sqr t{x}+1}\right)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

21/58.
