Solving for the minimum

Solving for the minimum 10 points minimize f(x) = 20 + x2-0.1 cos(2xx) Given the cost function f,, find the location of the minimum of fr, x". Store it as xstar and the corresponding f,(x*) as fstar Your submission should include a function f_rx and float s named xstar and fstar. Available techniques include: graphical, calculus (derivative Newton's method), or scipy.optimize.minimize Starter code (click to view) Answer* # Define f-r (x)- 3 # Locate ?xstar' and ?fstat
