y = -1/x rotates the curve in the x-axis
Picture y = -1/x as scaling the curve by a scale factor of -1.
so y=2x² doubles each y co-ord and since y=1/2x² halfs each, that has the same effect as doubling each x co-ord?
To enlarge the x co-ordinates of a function f(x), you need to change the function to f(ax), where 1/a is the amount that you want to enlarge it by.
I have a question here that asks to explain the transformations and sketch the graph of
