1. Population of the particular country was 23 million in 1984; in 1998, it was 31 million. Exponential growth function A=23e^kt explains population of this country t years after 1984. Use fact that 14 years after 1984 population increased by 8 million to determine k to three decimal places.
2. Draw graph of polynomial function. Illustrate all work and label intercepts. f(x)=x^3+2x^2-5x-6
3. Wrtite down form of partial fraction decomposition of rational expression. It is not essential to solve for constants. 2x-5/(x+2)(x^2+x-4)
