I have two questions here.
1. Find area of region that lies under curve y=(3x+4)1/2 over 0<x<4
(Those are less than or equal to signs)
2. It is estimated that t days from now a farmers crop will be increasing at the rate of .3t2+.6t+1 bushels per day. By how much will the value of the crop increase during the next 5 days if the market price remains fixed at $3 a bushel?
If you can do step by step, I really don't understand this.
