Y varies inversely as the square of x. So we can write the relation between x and y as:
where k is a constant of proportionality. It is given that y = 7/4 when x = 1.
Using these values, we can write:
So, now the equation in terms of x and y can be written as:
We are to find y when x = 3. So we can write:
Thus, for x= 3 value of y will be 7/36
