Setup the expression to find the area of the region bounded by y=x, y=x, x=0, & x=1.If f ( x) = In sinh (x] )) then find f (x) =15) A fruit fly population satisfies the law of exponential growth. On day 2, the population had 150 flies, whereas on day 4 that number became 300. Find the original number of flies in the population, i.e. the number when t = 0
