Use the definition of the derivative (don't be tempted to take shortcuts!) to find the derivative of the function f(x)=3−5x6+9x. Then state the domain of the function and the domain of the derivative. Note: When entering interval notation in WeBWorK, use I for [infinity], -I for −[infinity], and U for the union symbol. If the set is empty, enter "{}" without the quotation marks.

The u-drive rent-a-truck company plans to spend $13 million on 320 new vehicles. each commercial van will cost $25 comma 000, each small truck $50 comma 000, and each large truck  $80 comma 000. past experience shows that they need twice as many vans as small trucks. how many of each type of vehicle can they buy?
