Question 1153810: I have no idea where to start. Ive been out of scholl for 20 yrs. HELP!!!
1. the revenue function of a fictional cable company can be modeled by the polynomial function:

R(t) = −0.037t4 + 1.414t3 − 19.777t2 + 118.696t − 205.332

where R represents the revenue in millions of dollars and t represents the year, with t = 1 corresponding to 2001. Using MS-Excel, create a graph of the Revenue Function and determine over which intervals is the revenue for the company increasing? Over which intervals is the revenue for the company decreasing?
