Question 1194800
the initial population is 350.
when the growth rate is 2.3% per year and the loss rate is 1.9% per year, the growth factor becomes (1 + .023 - .019) = 1.004.
when the growth rate is 1.9% per year and the loss rate is 2.3% per year, the growth factor becomes (1 + .019 - .023) = (1 - .004) = .996 per year.
for graphing purposes, your formulas are:
y = 1.004 ^ x for a growth factor of 1.004 per year.
y = .996 ^ x for a growth factor of.996 per year.
the first graph shows the results of these 2 equations for the first 5 years.
the second graph shows the results of these 2 equations for the 20th year.
y = 350 * 1.004 ^ x is in red.
y = 350 * .996 ^ x is in blue.
the third display is the supporting data from excel spreadsheet.
