Quadratic and exponential functions: vertices, growth factors, and reading function values off graphs and tables of values.
Answer each question, then read why the right answer is right and why the tempting one is wrong.
Question 1
A drone's height above the ground, in meters, t seconds after launch is modeled by h(t) = -5t^2 + 30t + 4. What is the maximum height, in meters, that the drone reaches?
Question 2
A sample of a radioactive isotope decays so that 1/4 of the original mass remains after 18 years. Which function models the mass m(t), in grams, remaining after t years, if the original mass was 80 grams?
Question 3
A culture's population is modeled by P(t) = 1,200(1.08)^t, where t is in hours. Which of the following is closest to the number of hours it takes the population to double?
