Determine cosθ when tanθ= − √3 and sin(−θ)= − 3/√2

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)

Which exponential function has an initial value of 2? f(x) = 2(3x) f(x) = 3(2x)
