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?

scroll down to see the graph
you will see that the function monotone intervals are:
-infinity++%3C+x+%3C+6.56582+=>function increasing
at x+=+6.56582=> function has maximum
6.56582+%3Ct%3Cinfinity =>function decreasing
