Answer appropriately.According to data projections from a wildlife study, a certain region can support a population of 1380 coyotes when the human population in the region is 120,000. The coyote population falls by 15 for every additional 5000 people inhabiting the region. Express the coyote population in the region as a function c(x) where x is the number of people more than 120,000 inhabiting the region.
A. c(x) = - 
+ 121,380
B. c(x) = - 360x + 1380
C. c(x) = -1,725,000x + 1380
D. c(x) = - 
x + 1380
