Enter the missing values in the area model to find 8(7s – 2)

For the function, f(x) = -5x 2, find f(-4).

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)

The triangles are similar. what is the value of x? enter your answer in the box.
