The polynomial-7.5x^2 + 103 + 2142 models the yearly number of visitors (in thousands) x years after 2007 to a park. Use this polynomial to estimate the number of visitors to the park in 2021.

In that year approximately 2114 thousand people visited the park.

Step-by-step explanation:

Since the expression models the number of visitors in the park, where x represents the number of years after 2007 and 2021 is 14 years after that, then we need to find "y" for that as shown below.

In that year approximately 2114 thousand people visited the park.
