If y varies inversely as X^2 and y= -8 when x=2, find y if x=3.
First we need to find the constant of variation.
y varies inversely as is:

We can find the constant of variation by putting -8 in for y and 2 in for x and solve for k.

Our equation of variation is:

Now we can find y when x=3:

Happy Calculating!!!
