Apopulation of 70 foxes in a wildlife preserve quadruples in size every 10 years. the function y equals 70 times 4 ^ x, where x is the number of 10-year periods, models the population growth. how many foxes will there be after 30 years?

After 30 years there will be 4480 foxes.

Step-by-step explanation:

first period: (4) x (70) = 280

second period: (4) x (280) = 1120

third period: (4) x (1120) = 4480

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions
