Answer:

The function to represent this relationship will be:  [tex]y= \frac{15}{x}[/tex]

Step-by-step explanation:

[tex]y[/tex]  varies inversely with  [tex]x[/tex]. That means......

[tex]y= \frac{k}{x}..............................(1)[/tex]  

where [tex]k[/tex] is a proportional constant.

Given that, when [tex]x=3[/tex], then [tex]y=5[/tex]

Plugging these values into the above equation, we will get.....

[tex]5=\frac{k}{3}\\ \\ 5(3)=\frac{k}{3}(3)\\ \\ 15=k[/tex]

Now plugging this [tex]k=15[/tex] into equation (1).....

[tex]y= \frac{15}{x}[/tex]

So, the function to represent this relationship will be:  [tex]y= \frac{15}{x}[/tex]
