Question

The value of a car, C(t), t years after 2011, is modeled by the following function.

C(t) = 50,000(0.9)^t - 2,000

Which graph represents this function?

Answer 1

9514 1404 393

Answer:

  B

Step-by-step explanation:

At t=0, the value is ...

  C(0) = 50,000·(0.9^0) -2000 = 48,000

At t=20, the value is ...

  C(20) = 50,000(0.9^20) -2000 = 6079 -2000 = 4079

The only graph that matches these end points is B.
