Maths proportion question helpWatch this thread
For inversely proportional, we know the formula will look something like this. y= k/x, where k is a constant. Let's say for example that k is equal to 1, and x is equal to 0.01. So now we have y=1/0.01, which means y= 100. We do this when x = 0.02, y will equal 50. So when x is smallest, y will be greatest (and vice versa). If we plot a couple of points similar to the ones I just mentioned, you'll get a graph that looks like graph A.
We only have 1 graph left, which means graph C must be inversely proportional to the square of x.
