def f0(x):

return (-x**3+5*x**2-8*x+4)

define a function f(x, v) that takes in two inputs, x and v, and returns

f(x,v)=−x**3+5x**2−8x+4−v**2(2−x)

Note that for v=0, this function reduces to f0 above
This function represents a modification, or a "perturbation" of our original system
The size of the modification is represented by v

The roots of this polynomial represent the energy levels of the perturbed system.
