Must Do (3/14): Write an equation for each graph y=3(2^x) - 4 y=7(0.5^x)+1

Exit Ticket (3/14) Write an explicit equation and solve: This year, an estimated 4,324,000 people in this country are illiterate. With new incentives and funding, the country is hoping to cut that number by 21% every year. If this trend holds, how many people will be illiterate in the year 2035? (round to nearest one) y=4324000(0.79^x) 49,068 people in 2035

Must Do (3/15): Are each a function? Find the domain and the range The population of wolverines is increasing in Idaho by 5% every 3 years. If there are 80 wolverines this year, how many will there be in 2050? Write an explicit equation and solve. Domain: -∞≤x≤∞ Range: -5.5 ≤ y ≤ -2 2.5 < y ≤ ∞ Domain: -∞≤x≤∞ Range: -∞≤y≤∞

Must Do (3/16): Given 𝑓 𝑥 =35 −3𝑥 𝑎𝑛𝑑 𝑔 𝑥 = 𝑥 2 +4𝑥−5 Find f(-5) and g(-3) Find x if f(x) = 137 Find f(g(x)) A science class started out with 12 mealworms for an experiment. The population of worms will triple every month. How many mealworms will the class have in half a year? Write an explicit and recursive equation, then solve. f(-5)=50 , g(-3)=-8 X=34 f(g(x)) = -3x2-12x+50 y=12(3x) an = 3*an-1 , a0 = 12 After half a year, 8748 mealworms
