Solving <u>the quadratic equation</u>, it is found that the number of teams is <u>greater than 1000</u> after 3.1 years.
The <u>number of teams after x years </u>is given by:

Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:


Which has coefficients
, then:

We want the positive root, so the number of teams is greater than 1000 after 3.1 years.
