1a. To determine the population several years after and you have the growth rate and initial population you turn the growth rate into a growth factor then make an equation Y= initial value(growth factor to the x).
1b. The growth rate is the percent that the number is going up by and the growth factor is the number that you put to the xth power.
2a. You can once again make the equation and solve. It will be one less step from 1 because you do not have to change the percent to a decimal and then solve.
2b. You turn the number to a percent then subtract 100.
3. To find the time it will take an initial value to double you must find what x is so that the growth factor can equal 2 so it can double. Another way you could do it is by guessing and checking, you geuss for a number to be x and put the growth factor if it is over 2 it can work and you can try a smaller number.
