Answer questions

7. Mr. Stevenson asked his students to write an exponential function with an initial value of 10 that represents exponential decay. Circle the name of the student who correctly completed the task. AMANDA YING JANAE ROCCO f(x) = 0.25(10)x f (x) = 10(1.02)x f (x) =-5(10)* f(x) = 10(0.99)x Scientists have studied the population of insects in a certain area for several years and found that each year since 1999, the population increased by 12.5%. The initial population recorded by the scientists in 1999 was 350 insects. Use this information to mark 8-10 as true or false. If false, correct the statement in the space below. 8. The situation can be modeled using the formula y = a(1 - r)x. q. The value of a = 350 and r = 0. 125. 10. The function f(x) = 350(0. 125)* models the population of the insects x years after 1999
