Choice A will be a transformation of the function f(x) = x³. The parent function goes from the third quadrant through the origin into the first quadrant. This is not a cubic function.
Choice C will be a transformation of the function f(x) = x⁵. The parent function goes from the third quadrant through the origin into the first quadrant. This is not one of those functions.
Choice D will be a transformation of the function f(x) = x³. This is not a cubic function.
Choice D will be a transformation of the function f(x) = x⁴. These functions go from the second quadrant across the y-axis into the first quadrant. This is a quartic function.
So the question tells to express the expression in your problem where N0 is N-naught and the symbol represent the lower case Greek letter lambda. So the best answer or expression would be that the lambda is the wavelength of the expression. I hope you are satisfied with my answer
