(5) The number of deer in a National Park is modeled by P(t), where time t is given in years.

1070€0.23t

0.9 + €0.23t

P(t)

Use the Intermediate Value Theorem to show that the model predicts there will be exactly

1000 deer at some time t, where 10 < t < 15. You do not need to find the exact value of t

that gives 1000 deer.
