Question

The wolf population in a certain region 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)=41x +7 where x is the number of years since 2005. Using algebraic techniques, find the
value of x so that f(x) = 89.

Answer 1

x=2

Explanation:

f(x) is 89

f(x)=41x+7

89=41x+7

41x+7=89

41x=89-7

41x=81

x=81/41

x=2
