GE Net Income 2007–2011 The annual net income of General Electric for the period 2007–2011 could be approximated by P ( t ) = 1.6 t 2 − 15 t + 46 billion dollars ( 2 ≤ t ≤ 6 ) , where t is time in years since the start of 2005. 6 According to the model, during what year in this period was General Electric’s net income lowest? What was the corresponding net income? Would you trust this model to continue to be valid long past this period? Why or why not?
