This is the question from my test review, that I do not understand:

A company models its yearly expenses in millions of dollars using the equation f(t)=0.08t³-0.6t²+1.28t+3.7 where t=0 represents 1986. The company's account manager decides to adjust the model so that t=0 corresponds to 1996 rather than 1986. To do this, she obtains g(t)=f(t+10). Use the Binomial Theorem to express g(t) in descending powers of t.
