input: Write a python function to minimize the given objective function using scipy.optimize's minimize function.
  assert minimize_objective(5) == True
  assert minimize_objective(0) == True
  assert minimize_objective(-2) == True
output: from scipy.optimize import minimize
  
  def minimize_objective(x0):
      # Define the objective function to be minimized
      def objective_function(x):
          return x**2 + 4*x + 4
      
      # Perform the minimization
      result = minimize(objective_function, x0)
      
      # Return True if the optimization was successful
      return result.success
