Question 214950: The gray wolf population in central Idaho was monitored over several years for a project aimed at boosting the number of wolves. The number of wolves can be modeled by the function f(x) = 36x + 14 where x is the number of years since 1995. Identify its domain and range
The function's domain is x ≥
The function's range is f(x)≥

You can put this solution on YOUR website! The gray wolf population in central Idaho was monitored over several years for a project aimed at boosting the number of wolves. The number of wolves can be modeled by the function f(x) = 36x + 14 where x is the number of years since 1995. Identify its domain and range
The function's domain is x ≥
"Domain" specifies what values of 'x' can take for the equation to hold true.
In this case, x can't be negative because if x=-1, f(-1) = -22 -- well, you can't have -22 wolves. So, the domain, has to be values of x where f(x) remains positive:
x ≥ 0
.
The function's range is f(x)≥
"Range" specifes the values of f(x) can be based on the above domain:
f(x) ≥ 14
