A large pharmaceutical company uses the function f(x)=1.438x−2908 to model the amount of​ money, in billions of​ dollars, it spends each year on research and​ development, where x corresponds to the year. Use the function to predict the amount of money it will spend in 2025.

To predict the amount of money the pharmaceutical company will spend in 2025, we need to substitute x = 2025 into the function f(x) = 1.438x - 2908.

f(2025) = 1.438(2025) - 2908
f(2025) = 2910.75 - 2908
f(2025) = 2.75

Therefore, the company is predicted to spend 2.75 billion dollars on research and development in 2025.
