consider the basic function y = x^2
y = 7x^2 = (√7 x)^2 has been scaled by a factor of 1/√7
y = 1/4 x^2 = (1/2 x)^2 has been scaled by a factor of 2
y = -2x^2 = -(√2 x)^2 has been scaled by a factor of 1/√2
So now just sort the scale factors
y = 7x^2 = (√7 x)^2 has been scaled by a factor of 1/√7
y = 1/4 x^2 = (1/2 x)^2 has been scaled by a factor of 2
y = -2x^2 = -(√2 x)^2 has been scaled by a factor of 1/√2
So now just sort the scale factors
