Population Dynamics and Linear Functions

The video tutorial explains the linear decline in the population of a small town in Central Florida from 1992 to 2000. It demonstrates how to formulate a linear equation to express the population as a function of time, using ordered pairs to calculate the slope. The tutorial derives the equation and uses it to predict the population in 2004, showing a decrease of 510 people per year.

What was the population of the town in 1992?

• 44,200 people

• 40,120 people

• 50,000 people

• 42,000 people

In what form is a linear function typically expressed?

• f(x) = mx + b

• f(x) = a/x + b

• f(x) = x^2 + bx + c

• f(x) = ax^2 + bx + c

• -510

• 510

• -400

What does a negative slope indicate in the context of population change?

• The population is stable

• The population is fluctuating

• The population is decreasing

• The population is increasing

What is the linear equation for the population decline?

• p(t) = 40,120 - 510t

• p(t) = 44,200 - 510t

• p(t) = 40,120 + 510t

• p(t) = 44,200 + 510t
