Each female of a particular fish species produces millions of eggs per year. Draw and label the most likely survivorship curve for this species, and explain your choice.
52. \(f\left( x \right) = {\left( {{x^2} - 4} \right)^3}\)
50. \(h\left( x \right) = 5{x^3} - 3{x^5}\)
In 2014, the United States had a population of 320 million people. If the (annual) per capita change in population size (r∆t) was 0.005, how many people were added to the population that year (ignoring immigration and emigration)? What would you need to know to determine whether the United States is currently experiencing exponential growth?
