The iPhone X is valued at $1000 upon purchase. The value is expected to decrease by 14% each year. Which function matches the situation? Let Cost (C) be a function of time (t)

• C(t)=1000-0.14t

• C(t)=1000(.14)^t

• C(t)=1000(.86)^t

• C(t)=1000-0.86t

Dana and Dona made model rockets. Dana has Rocket 1 and Dona has Rocket 2. Both launch their rockets at the same time. If both rockets continue to increase in height at their same rates, which rocket will be the highest at 40 seconds. Rocket ​ (a)   will be higher, because it is a(n) ​ (b)   function. Rocket ​ (c)   is a(n) ​ ​ (d)   function.
