y ıs ınversly proportıonal to x^2
when X=4 Y=3
find y when x =5

First step: y=k/x^2

Second step: substitute with values that are given to find k (constant) 3=k/4^2 3=k/16

Third step: find k normally by multiplying 4^2 (16) by 3 to give you k=48

Fourth step: now you should find the Y by Y=k/5^2 y=48/25 so Y = 1.92
