Find the function f given that the slope of the tangent line to the graph of fat any point (x, f(x)) is f ' (x) and that the graph of f passes through the given point. F' ( x ) = 2+1; X (1, 3) f ( x ) = [-/0.3 Points] DETAILS The total number of acres of genetically modified crops grown worldwide from 1997 to 2003 was changing at the rate given below in million acres/year. R ' (t) = 2.178t2 - 18.28t + 50.53 (0 s ts 6) The total number of acres of such crops grown in 1997 (t = 0) was 36.7 million acres. How many acres of genetically modified crops were grown worldwide in 2003? (Round your answer to the nearest whole number.) million acres
